Install the zero filter. Air filter zero resistance (nulevik), its pros and cons

The ambiguous attitude towards tuning the air system is consumed by car enthusiasts, seeking to get a maximum from their car. This is due to the installation of such an element as an air filter of zero resistance (VFNS). Unlike professional athletes who unequivocally belong to such a detail, lovers did not come to a common opinion.

The name itself speaks about the functions of the product. In fact, he determines the manufacturers as much as possible by the resistance of the air entering the engine to form the fuel and air mixture. Due to its design, the amount of air increases, and the mass of the oxygen is increasing with it. The meaning of the installation of this unit is reduced to an increase in the power of the vehicle.

Filter installed

It is believed that zero gives an increase of about 5-7% of power. In terms of middle car, It turns out about 5 hp

It is unlikely that such a parameter can be called essential. Not all experienced drivers Will be able to feel like an increase. Therefore, the main buyers of new items are representatives of the young generation of car owners. Most often, the device is equipped with domestic manufacturers.

Installation of VFNS is usually carried out during the tuning of the power plant. Because the filter without the preparation of the motor will not bring the desired effect. It is recommended to put a straight-flow exhaust, and only then mount the nulevik. Additionally, the throttle valve is changed to more powerful. Also reflash "brains" under the updated design.

As a result of the work done, it is possible to hope that additional five horses will be added to the power.

A variety of filter forms

After performing such manipulations, a little sound published by the engine will change. The solid engine bass can felt the pride of young drivers, and will allocate the car "voice" in the transport stream.

Positive and negative sides of the installation of zero filters

Each business has positive and negative consequences. Let's try to evaluate the pros and cons of the zero resistance filter installed in the car.

Pros:

• increase the power of the car when conducting additional work with exhaust system;
• new, more "solid" sound from open space;
• the updated type of pumproom space stylized under the sports car.

Minuses:

• need regular care for the installed filter;
• cheap non-phoned filters carry out low-quality air purification, which negatively affects operation motor oil; It becomes dirty, and this leads to crying consequences with the engine as a whole.

The difference between ordinary and zero filters

Performing air purification by zulevik directly depends on its structural features. Standard air filters are made of knowingly dense materials. Due to this, they are qualitatively cleaning the air supplied to the system, from various dust polluting particles and garbage. But at the same time, a significant resistance of air is obtained due to the high density of the filter layers.

The difference between filters

Zero filters based on cotton fabric. An additional restraining factor for garbage is a special tissue impregnation. Thanks to such a design, small particles of dust and dirt do not penetrate inside the motor, but remain outside the filter.

In fact, cleaning occurs due to the adhesion of the garbage, while the air does not interfere anything else.

This design does not create 100% cleaning. Also, if you do not clean the filter on time, it will be more negative than a positive from this installation.

Maintenance of zero resistance filters

After installing the nulevik, it is necessary to take care of it. Required with a certain fixed frequency of mileage mileage to wash and impregnate filter. For impregnation, a special fluid is used, which is purchased separately.

Wash Nulevik

Saving service is not worth it, otherwise the car will worsen its power characteristics, and the fuel consumption will noticeably increase.

The order of service is:

• the filter must be removed from the car, then a brush with a soft pile or a brush with a non-rigid bristle is removed from the visible particles of dust and garbage from the surface;
• a layer of impregnation from the branded cylinder is applied to the dry purified filter and 10-15 minutes leave for complete impregnation of the fabric;
• now the nulevik is lowered into the container with water room temperature and pumped in it;
• removed from the tank and is substituted under a weak flowing jet of water for flushing;
• excess water should be smoldering and put the device for a short drying;
• after that, the filter can be installed in place.

You need to know that drying with a hair dryer or similar intensive devices is not allowed.

Cleaning under running water

The average mileage between the service is 8-10 thousand kilometers. If the operating conditions of the car implies travel along dusty roads, then the mileage decreases to 4-5 thousand kilometers.

For VFNS, there are about two dozen flushing cycles. Next, it is recommended to replace the zero resistance filter to the new one.

Self-making filter

The estimated price of the product in stores ranges from 500 to 3,500 rubles without taking into account the cost of impregnation. Not all car owners are ready to pay a rather big price for such an additional device. Therefore, the craftsmen make a filter of zero resistance with their own hands in garage conditions. Most often, the "VAZ" classic or models of old Muscovites are as an experimental car.

Step 1. Cut the filter cover by diameter Step 2. Customize the filter cover Step 3. Clean the edges on the sandpaper Step 3. Conduct measurements and facing sizes Step 4. Prepare the filter Step 5. Cut off the unnecessary bodice nozzle Step 5. Clean the edges Step 6. Mount to the engine

As wellfight materials, regular filters and body parts of car air systems are used. The alteration is carried out with the help of a grinder, sandpaper, a file and hard work. Operating conditions apply to about the same as for branded products. But the installation on the car such a detail is carried out at your own risk. There are no irreversible changes in the design in the design, so if you wish, everything can be returned to the original position with "native" filters without prejudice.

Good day. The topic of today's article is the air filter of zero resistance, its pros and cons. Traditionally, for our site, the article contains a large number of photos and video materials and contains a detailed answer.

What is nulevik (zero resistance filter)?

The classic air filter looks like this:

It is usually made of special paper and filters by micropores. Particles more than a certain size simply cannot penetrate inside.

Naturally, the filter is gradually clogged during operation, the resistance to the air flow increases, and the engine power drops. 2 (usually every 20,000 km) filter replace new.

The zero resistance filter looks like this:

It was made of special extruded fibers and works somewhat more complicated than its paper analogue. Fibers are soaked special fluid, the air passing through the filter to strive to pass along the path of the smallest resistance (through fibers) and dust from the air, sticks to the fibers due to special impregnation.

Yes zero resistance filter really has less resistance Airflow, but if you skip, then, do not rinse the filter and do not impregnate the special liquid - all dust will fly straight into the engine!

Pros from zero resistance filter:

• reduced air flow resistance on the inlet
• long service life (100,000 km or 20 flushing every 5,000 km)
• most available tuning Technical Part

Cons from installing zero resistance filter:

• noise on inlet
• the need is frequent
• when passed the planned dust falls into the engine, and it fails
• the need for an inlet tract (on some injection engines)

Here is a pretty busy video about zero resistance filters:

Does it make sense to install the zero resistance air filter on a standard car?

For everyone modern cars The intake and graduation path are designed for a specific operation mode and on a certain air flow and inlet resistance. I think many have heard about the "setting" of the intake and the "setting" of the issue. The author of this article was previously engaged in Svapoy Toyotovsky engines in the domestic auto industry. Specifically, we were popular to install an engine 1UZ-FE in the Volga.

It looked like this:

So - when we collected the inlet ourselves that Used a regular Volgovsky filter and random configurations of air ducts, as a rule, the engine "elated" is more than 20 liters of gasoline, when installing the standard filter from Toyota, the consumption came to normal.

So it turned out due to the fact that the standard system of measuring flow and air temperature could not work with a non-standard filter. Those. Our replacement of the filter forced the engine control unit to make the fuel mixture richer, while the dynamics had worsened and the consumption increased.

Installing the zero resistance filter on not prepared for this injector Engine deprived of meaning. For each concrete Engine You need to count the consequences! And most importantly - if you forget to spend the filter, it will very quickly come into disrepair and starts to skip the dust into the engine, and then, dust will make its black business - and it will be required to be expensive overhaul.

The filter of zero resistance and carburetor engine - Is there any sense?

Colleagues, the carburetor works on the Bernoulli effect, i.e. The greater the air pressure difference at the inlet and outlet of the carburetor, the better it will be able to dose the mixture (the operating pressure range will expand), and any decrease in the inlet of the inlet is good, the engine power with a carburetor power system during the transition is not a zero resistance filter! But do not forget to serve the filter.

By the way, Order a zero resistance filter You can directly at the manufacturer.

I have everything today. I hope that the article "Air filter of zero resistance pros and cons of use" completely uncovered the theme. If you have questions left or you want to add an article - Write comments.

Hello everyone! In turn, we have a fairly relevant and interesting topic. After all, we will talk about the nulevik filter. Many have heard about such an air filter, but not everyone knows exactly what it is for what is needed and what is it in him.

Nulevik put instead of air filter in a regular place. And it is important to understand what a similar device gives. Immediately make a reservation, then it has a plus and cons. But for objectivity I will try to talk in detail about the device first, and then summarize whether there is a benefit in this purchase, is it worth installing a nulevik for a car, on a moped, on some VAZ or on the carburetor, for example. After all, the network is very often the craftsmen who put a device for Pidburg and Alpha, that is, on a scooter.

Do not forget to share your opinion. Especially if you have personal experience In applying zero resistance filters. It is so correct to call zuleviki.

Why it is necessary

To begin with, we will understand what it is and with what it is eaten. A standard or ordinary air filter is designed to clean the air entering the engine, from all kinds of contaminants. It is by air filtering that the power loss occurs.

It is determined by the fact that the cleansing elements in the filter design (usually special paper) create resistance to air flow. It is not surprising because the filtration material is very dense. And the greater the resistance indicators, the greater the total power is lost. As you know, the increase in power is achieved by increasing the amount of incoming air. It is here that the scene comes out a zero resistance filter.

Nulevik is an alternative for a standard cleaner. Its design is such that the device reduces resistance to the inlet, while not sacrificing the air purification itself. Thus, the increase in power is achieved.

And then there is a natural question about whether your prior is worthy, VAZ 2112 or VAZ 2114 of this element? Is it worth buying a nulevik at all, wanting to slightly increase the engine power?

Practice and research show that such a small tuning as a zero setting allows you to get an increase in 3-5% of power. If it is a low-power car, then you definitely do not feel the increase in several horse power. Also, you will not see any difference in dynamics. But the numbers will be higher than you can comfort yourself.

Key advantages

Reading reviews on zuleviki, I met a lot of contradictory opinions. One put himself such a filter on the injector, and remained very satisfied. Another spent a bunch of money on a nulevik from K & N and its installation, wanted changes, and in the end I received only in vain the time spent. And such examples mass.

I will say right away that you do not have a problem from auto shops from auto shops. The price of some models is quite adequate, therefore it is not difficult to buy and relatively inexpensive. But whether such an element needs to install on Vaz with their own hands, the question is extremely interesting.

Let's start with good. Like any device, the nulevik has its pros and cons. By minuses include the cost in comparison with the usual air filter and the need for permanent cleaning.

As for the advantages, there are several of them.

• Increases power. Nulevic has a complex design that allows reducing resistance. This gives an increase in the number of horsepower;
• Simultaneous cleaning efficiency. Although the resistance drops, this does not affect the quality of air purification;
• Replacement frequency. Change nulevik as often as an ordinary filter, no need. For them, the possibility of washing. This allows you to return performance features fully;
• Posterness in characteristics. Let a little, but nulevik adds power and increases torque;
• Sound. For many, it is important not power, but a sound characteristic of powerful motors. Nulevik creates such an effect, and in the end the car sounds very interesting.

To achieve the desired one, you will have to remove the standard filter, and in its place to establish the device of zero resistance. What is better to buy and install with your own hands, or give the car to the masters, decide for yourself. In the second case there will be a quality assurance and a competently selected filter. The main thing is that the specialists themselves are qualified and reliable.

And clear something

There is a common misconception, according to which, after removing the filter and the case, it is possible to significantly increase the engine power. This is absolutely not true.

It is important here to take into account that when developing the engine is made a thin calculation of the phases of gas distribution, in which the errors and losses on the filter are taken into account. And if dust starts into the engine, it will not be able to work for a long time. Here it is necessary to have a fence that will prevent the penetration of pollution. It is possible to reduce resistance by expanding the passing holes. But then the filtering quality will decrease.

Before looking for the article and buy a nulevik on your motorcycle or car, remember one simple truth. For cars without a powerful sports engine, the cost of buying such a filter will be absolutely meaningless. You will only spend in vain several thousand rubles. The only thing you get is a bit modified motor sound.

Zuleviki is suitable only for sports cars and cars with powerful power plants. It is allowed to use such a filter on serial motors only in cases where a comprehensive refinement is carried out. That is, a boring is done in the cylinders, an increased throttle is mounted, installed sport camshafts And so on here with them in the kit you can put nulevik.

Question of service

If you still decided to install a nulevik instead of a standard type air filter, then it will have to further care. The essence of care lies in cleaning and periodic impregnation with solutions. Moreover, a certain technology is strictly observed.

If this is not done, fuel consumption will significantly increase on the car, the power will fall and the car will begin to respond poorly to the increase in speed when the gas pedal is pressed.

You need:

• remove the filter;
• soft brushing Clear Pollution;
• remove dirt from the landing socket;
• rinse with water filter;
• shake several times, and not dry;
• apply a cleaning agent on both sides;
• install in place.

If the machine is operated in sufficient hard conditions, then such prevention is carried out at least every 8 thousand mileage kilometers. For normal conditions, 10-12 thousand km is enough. One nulevik can be flushed to 20 times. Then mandatory replacement.

What can be said about such zero resistance filters? In the photo they look spectacularly, it is expensive and in theory possess important advantages over standard filters. But in relation to serial machines they are useless. It is a fact.

Nuleviki is relevant to put on powerful sports engine engines and motors that are subject to serious technical tuning. By itself, the weather filter will not do on motors, the power of which does not exceed 120-150 horsepower.

The zero resistance filter is a detail that makes the supplement in the engine of the car when tuning. These items are quite accessible to the consumer and easily installed in the motor. They have different versions, and also look decently. Studying all the pros and cons of the zero resistance filter, you can decide on the need to install it on the motor's motor.

If you wish to add a few "horses", then you know that almost every process of improving and tuning the engine does not pass without a trace. And in the overall plan of the processes of processes, this is a notable increase in the power indicators. Any engine tuning does not cost without refinement of the air supply system, on which the motor efficiency depends on. The zero resistance filter, the reviews about which are mainly positive, due to their excellent ability to pass the air affects the formation of fuel-air mixture.

Purpose

Simply put, the main function of any air filter is from various unwanted impurities. This element should protect the piston group and cylinders from the possible dip and moisture in them.

At the same time, having good car Loses its power. Due to the dense paper flow of consumed air faces serious resistance and worse passes through the filter. Therefore, at high resistance, the power of the power unit is lost. And at that moment, when he clogs, the fact of loss of power indicators is especially noticeable. The zero filter has a specific design, which contributes to high-quality air purification, but at the same time significantly reduces the resistance of the air flow at the inlet, which, in turn, contributes to an increase in power. As a rule, the installation of a zero resistance filter occurs on all sports and racing cars, in order to add several additional horsepower to their motors. Given the fact that this element of the engine equipment can be easily purchased in auto parts stores, many motorists are installed on the motors of their cars zero filters.

Maintaining it in suitable condition

Like any other element, this filter needs cleaning. To do this, it must be dismantled and with the help of a special brush carefully cleaned all the surfaces of the element. Next, you need to apply a special cleansing agent on the surface of the filter and ten minutes to withstand until it is absorbed completely. After that, the filter element should be washed and rinsed under running water.

When operating a car in normal climatic conditions, the washing is recommended to do every ten thousand car runs. When using transport at less favorable conditions, cleaning is carried out every five thousand. By washing about twenty times, the element should be replaced with a new one, since the working resource is fully exhausted.

Pluses of zero resistance filter

An increase in the amount of air supply passing through it provides power installation Large oxygen required for normal burning fuel mixesWhat ultimately increases power.

It is necessary to note the factor that by setting the zero resistance filter on the VAZ, expect a decent power absorption. On small-liter engines, the increase in the power indicators is almost unnoticed, unless, of course, do not consider diagnostic indicators in digital equivalent at special stands. And, for example, on aggregates of 3 and more liters, the factor of increasing dynamic indicators is sufficiently noticeable, it is on such engines all the positive qualities and the advantages of such an element of air purification are revealed.

The second positive feature of the filter can be called a change in the sound of the engine, which is coming from under the hood. Due to the design features of the nulevik, the sound characteristic of sports cars is listened.

Changes I. appearance Engine. Some motorists establish such an element due to aesthetic species and aggressive sound.

disadvantages

The disadvantages of zero resistance filter have a slight character, but still they exist. First, it is the need for constant care for the state of the filter element. Second negative factor You can call poor-quality air purification from impurities. Often it can happen if an element is inexpensive and less qualitative than expensive analogues.

Pros and cons filter zero resistance on a vase

One of simple ways Tuning car VAZ models is to install on the engine zero filter. At the same time, the issue price is not very high, and the installation can be carried out on their own. Installation on the motor VAZ-2110 zero resistance filter is as follows. To begin, disconnect the rubber pipeline from this can be done using a conventional screwdriver. Next, you need to remove the sensor fastening from the standard air filter housing and remove the element itself. Then you need to disconnect the negative wires from the head of the cylinder block. Connecting the mounting bracket to the engine housing. Fix the air sensor fastening bolts to the filter mounting bracket. We install the sensor on the part, and finally connect the air sensor connector. How to look in motor compartment zero resistance filter?

The photo indicate that this adaptation perfectly fits into the overall appearance of the power unit and gives it a certain aggressive nature.

Filter K & N

Products of this manufacturer firmly settled on automotive market And have a huge number of their admirers.

The K & N zero resistance filter was designed in California by the company of the same name to promote an increase in power values. In terms of its characteristics, the product of this manufacturer is largely ahead of their analogues of competitive firms. According to the developers, its installation on the engine will increase the power indicators for integer four "horses". The element can be used for a long time, and during the operation of the car in ordinary urban conditions, it can be performed only after 80 thousand km of car run.

K & N is made of purest cotton.

The main parts of the element consist of several cotton layers, which are located between two aluminum plates. To improve the performance of the filter, it is impregnated special Oil, And his constructive features Provide durable and reliable operation on any engine.

All products of this manufacturer have warranty period Services, which, according to the company's engineers, is one million miles.

Views

There are two types of zero filters, which differ in the geometric shape and installation method. The first are cone-shaped. This type of filter is very effective, as it is located under the hood without an additional protective case. Also, its advantages increase using smooth connections to it with a minimum amount of bends, in contrast to corrugated. The second is the elements installed in the regular seat.

Installation

How to install zero resistance filter? Reviews of motorists say that it is desirable to choose the most "cold" place under the hood of the car. It is necessary so that the air has been able to be cold.

It is undesirable to place a filter next to the radiator and collector exhaust gasesBecause of this, efficiency is significantly reduced.

For the fencing of the element from the possible way into it, the engine oil is recommended to install a protective cover on it.

What is the result?

Having considered the pros and cons of the zero resistance filter, the owner of the car will decide on the installation of this element. If you still decide to equip the engine of your "iron" friend with a filter of this design, then the selection and installation of the nulevik should with the correct approach to this procedure, in order not to damage the state of the power unit. Professional racing cars are equipped with such a product in a standard order, because on their powerful motors the action is very noticeable. When the car moves at high speed, the air flow creates a turntive in the intake path, practically turning into a small hurricane. Due to this factor, the system creates the moment of vacuum, with which the zero filter is perfectly coping with, straightening the air flow.

In this case, the probability of dust falling into the engine cylinders is very large. For racing cars This is irrelevant, since almost after each competition their engines are repaired and replacing the piston group.

Conclusion

The pros and cons of the zero resistance filter depend on the quality of the execution and the materials used in the manufacture of those, on the type of product itself and the car engine. Therefore, the final decide on the installation depends only on you.

The purity of the air supplied directly affects its resource and power. Therefore, the intake systems are supplied with filter elements. At the factories, the overwhelming majority of mass models of cars are supplied with paper filters, which due to the small size of the pores in the material reduce the air flow rate, which negatively affects the efficiency of the filter operation.

There is an alternative - zero resistance or zero filters. First of all, they differ from the standard paper, a much larger pore size, which do not particularly affect the flow rate and the presence of impregnation. Contaminating particles leave the air flow when it is bent in the labyrinth of the zulevic structure and, due to the impregnation, they stick to the walls of his pores.

According to the manufacturers of manufacturers, the above features of the operation of zero should increase engine power. And they, depending on the good faith of manufacturers, type of engine and a number of other factors, even cope with this task.

What does the zero resistance filter look like or nulevik.

From a constructive point of view, there are two types of zero resistance filters. The first is mounted in a regular place in the intake box, the second - immediately before throttle valve With the dismantling of the entire preceding path. Both types are several layers of textile material impregnated special compositionIt is customized to call oil. Textile material has a more porous structure in comparison with paper, and the oil holds particles of pollution in its thicker.

Depending on the quality of the materials used varies and the cost of the part. In this case, the cone-shaped filters mounted before the throttle is usually more expensive than flat, installed in the regular place of paper filters.

One of the features of zero resistance filters is the need regular maintenance. In order for a clogged filter in the process of long-term operation, the engine does not harm the engine, every 3-5 thousand kilometers of the mileage is recommended to rinse it and update the impregnation. Specialized stores offer a wide range of flushing and impregnation compositions. On the other hand, it is easier to replace the paper filter once every 10 thousand km than every two wash and re-impregnate the nulevik.

It should be noted that the continuous use of impregnation filters with MAF or MAP sensors installed immediately after the filter is fraught with a serious engine breakage. The intensive flow of air blows the oil that settles on the sensor and distorts its testimony.

What gives a zero resistance filter

Installing the zero resistance filter, depending on the type of engine and its initial power, issues various results:

1. On turbocharged engines of noticeable power output is not detected.
2. Atmospheric power units Low power show an increase from 2% to 5%.
3. With a successful coincidence of the circumstances and the use of high-quality filters, the increase can be 7%, but this growth will be episodic.

Thus, no tangible growth of horsepower is observed, because the driver feels the difference more than 10%. Therefore, installing a reduced resistance filter is or hunting for numbers, or not the most essential part of the complex tuning. In fact, a greater increase in power can be obtained simply by reducing the weight of the car.

Pros and cons filter zero resistance

Nulevik under the hood.

Naturally installing the filter of zero resistance - not quite meaningless business. Especially if you do not pay attention to power parameters. Like any other technological solution, it has strengths and weaknesses.

Advantages of nulevikov

• Be that as it may, they increase the power of the engines. Especially small atmospheric. Yes, the increase is minimal, but it is.
• Filtration with a smaller reduction of air flow speed optimizes fuel consumption.
• There are models for installation in regular planting Without modifications.
• The cone-shaped models allow you to dismantle the intake path up to the throttle, which frees the place under the hood, say, to install the overall turbine.
• Appearance characteristic sound Engine operation with zulevik. Although this is a purely decorative advantage that does not affect power.
• A longer service life due to the possibility of periodic service, and not replacement.

Disadvantages of zulevikov

• Much more high price Compared with regular paper filters. The cost of branded models reaches 150 dollars, while a typical bumba filter can be purchased for 200-300 rubles.
• The cone-shaped filters work with hot air from under the hood, which can negatively affect the motor status and other nodes.
• Non-permanent and dubious efficiency, which depends on a variety of factors, and sometimes absent.

Given the above information, you can equate the use of a zero filter to a piece of plastic, fixed above the knitting of the bike. Only instead of a bike car, and instead of plastic - a detail cost from 2000 rubles. After all, the essence of tuning, first of all, in increasing power, and not in decorative changes.
