How to choose vaz spark plugs. How to choose spark plugs

Today we would like to tell you which spark plugs to choose for the 2114. There are enough spark plug manufacturers to choose one or the other.

Domestic or imported spark plugs

Among the most popular candle manufacturers, there are several leaders who are in high demand and have proven themselves from the best side.

These candles are installed by the manufacturer from the assembly line and at their own expense. great option... However, according to the reviews of motorists, a marriage comes across. Therefore, when choosing these candles, it is worth checking them immediately before installing.

• A-17DVRM (1.0) engineer. 8-cl - candles for injection 8 valve engines.
• AU-17DVRM (1.0) engineer. 16-cl - candles for injection 16 valve engines

Candles Brisk Czech Republic

Brisk candles of good quality, which have proven themselves with positive side are in high demand. Brisk has 10 series of candles, differing in their design and intended for different types engines not only on cars, but also on motor vehicles.

• BRISK SUPER FORTE LOR15YC-1 spark plugs for 8 valve
• BRISK SUPER FORTE DOR15YC-1 plugs for 16 valve

The gap for both types of candles is 1.1

DENSO Spark Plugs

The Japanese quality of candles needs no introduction. These candles are installed by manufacturers on some imported cars... Judging by the reviews, quite good candles from a higher price category than the previous ones. However, one should beware of counterfeits, which are now abundant.

• DENSO W20TT Spark Plugs - for 8 Valve Engines
• DENSO W20EPR-U11 plugs - for injector 8 valve

Candles NGK

One of the leading companies in the production of spark plugs, glow plugs and other auto components. The candles are of excellent quality, which are installed on the conveyors of manufacturers such as Nissan, Mazda and others. Judging by the reviews of motorists, the NGK candles installed on their cars worked on average 25-30 thousand km.

Spark plugs NGK No. 13 BPR6ES-11 for injector 8 valve. Cost 450-500 rubles set

Before installing new spark plugs, check that they are working properly. This can be done using a special device, or at the stand.

If you have unstable work motor, he began to "troit" it is quite possible that the time has come to replace the spark plugs, either PVN or. So, first, let's check the spark plugs, most often the reason is in them.

• We remove the tips of the PVN from the candles
• We unscrew all 4 candles (you need a key for 21)
• We put on the tip on the candle and lean it against the metal (it is possible to the body of the engine block)

Attention! The candle is under high voltage at this moment, so it is better to hold it with pliers or something similar.

We begin to turn the starter and look at the candle, if there is a spark, then the candle is working. We do the same with other candles.

Spark plugs are an essential attribute of any car with gasoline engine... The Russian winter is a real test for these details. It is during this period of the year that the candles fail more and more and drivers begin to think more carefully about which candles are better for the VAZ. It is on this topic that we will talk today in more detail.

Today, candles on the VAZ 2107, which are usually put by car owners, are made in Europe and Japan. Unfortunately, drivers have little confidence in domestic candle manufacturers. In this review, we will describe several candles widely available in our market.

Overview of candles for VAZ

• Three-electrode Japanese candles NGK BUR6ET are a very common option. Bench tests show good stability of the engine and a good increase in power - 4.4% (all the above parameters are indicated in comparison with the "native" VAZ spark plugs EZ A17DVRM). They are also economical in terms of gas mileage (3.9%). Here are the best candles for the VAZ2114.
• French candles Beru Ultra-X 79 (4 electrodes) are the least toxic of all the candles that have passed bench tests and described in this article. In addition, these spark plugs showed the highest fuel economy (4.2%). However, they are somewhat inferior to their Japanese counterparts in terms of stability and power gain (only 3.7%).
• The most stable were Czech three-electrode plugs Brisk Extra. In addition to stability, they provided a significant increase in engine power - by as much as 4.8%. However, their serious disadvantage was the insignificant savings in gasoline. When deciding which candles are best for Kalina, many stop at this option due to its reliability.
• The best indicator of power gain (> 6%) among the tested samples is possessed by single-electrode Finwhale plugs. At the same time, they slightly differ in resistance from Brisk Extra and are compared in this parameter with Japanese candles NGK... At the same time, their economy and toxicity indicators are even worse than those of Brisk Extra.
• German Champion spark plugs have combined efficiency (4.2% like Beru Ultra-X 79) and good power gain (5.6%). They have the same medium resistance as Beru Ultra-X 79, inferior to all other samples.

When deciding which spark plugs to choose, you need to consider what you want from them. If the main thing for you is reliability, then your option is Brisk Premium, Finwhale or NGK BUR6ET. If you care about fuel economy then take Champion, Beru Ultra-X 79 or NGK. The Finwhale plugs will provide maximum performance (thus reducing the economy) and Champion (the power will be slightly lower, but the economy is much higher). In general, the best candles are original, that is, genuine. Unfortunately, today, without knowing it, you can buy a lot of fakes, which sometimes make drivers disappointed in the products of good firms.

In addition, when servicing the VAZ 2110, which better candles, The technician will tell you, because this is not such a serious problem as the frequency with which you need to change them. This should be done every 15-20 thousand km.

Regarding the resource, the picture is quite simple here - first the spark works with one contact with minimal resistance, then as it wears out, the resistance begins to grow, so the spark goes to another contact and continues to work confidently smoothly. Thus, the resource, as practice shows, can increase two to three times. On some cars, such options go 100 - 120,000 kilometers.

YES and the formation of eggs is a little different here, see the pictures.

The only weak link is the central electrode, it also wears out and as it wears out, the candle starts to work worse.

My review

Unfortunately, I have no photos and video material from the tests of such candles. But I had experience. On a working VAZ 2111, multi-electrode options (three contacts) were purchased from BRISK, the name - if my memory serves me EXTRA. The price of the issue is about 180 - 200 rubles - a piece, they did not buy expensive NGKs, for our old working VAZ, this is too much. The car moved with them about 40,000 kilometers, then another unit took it and I could not track it. According to the driver, the start in cold weather has improved (even not on a new battery), the throttle response has increased slightly, the consumption has dropped, slightly, but it has fallen - if you believe on-board computer, then this figure is about 0.3 - 0.4 liters, which is about 4% savings. After 20,000 kilometers, we unscrewed a couple of pieces and saw what happened to them and you know everything was in order, I know the mileage is small, but the first impressions have already formed. Therefore, the effect of them really is. Also watch the video I shot just for you, I found a worn version from BERU.

Test

On the Internet, I dug up information about testing multi-electrode spark plugs, I want to offer you the best five.

Manufacturer - FRANCE. For the moment, the best of them all. The price of the issue is 600 - 700 rubles a piece.

The structure - 4 electrodes, paired with different gaps to the central contact, two electrodes - 0.8 mm, two more 1.2 mm. Thus, they are suitable for many vehicles, be it a carburetor or an injector.

After tests: engine power increased by 3.7%, consumption fell by 4.2%, toxicity by 4.5%

Manufacturer - JAPAN. They take the second place, slightly yielding to BERU, the issue price is 500 - 550 rubles / piece.

Three electrodes that have the same gap of about 1.1 mm, making them preferred for injector applications. Sufficiently high quality, second only in fuel economy - there are only 3.9%, but the rest of the characteristics are practically the same power - 3.7%, toxicity - 4.5%

Manufacturer - EUROPE. Third place, the issue price is 400 - 450 rubles / piece.

Three contacts, approx.1.1 mm gap. Made with high quality, consumption fell by 3.5%, power increased by 3.4%, toxicity decreased by 4.0%

Manufacturer - CZECH REPUBLIC, 4th place, price about 700 rubles / piece.

We used a new technology in a building where the side 4 electrodes are lowered lower than the central one. That is, the spark seems to "slide" over the insulator, as it seems to me, because of this, the resource will be slightly reduced, however, in our test, it takes the fourth step in terms of consumption (decrease - 3.1%), increase in power - 3.0%, toxicity (decrease by 3.5%)

Recommended candles for Priora / Kalina / Grant... The manufacturer recommends using domestic spark plugs А17ДВРМ and А15ДВРМ or their imported counterparts. Different spark plugs are used depending on the engine model. For example, candles on Prioru 16 valves: AU17DVRM, and for 8 valves: A17DVRM. Spark plug compatibility table for all VAZ cars:

• Lada Priora: 21120-3707010-00, 21120-3707010-01.
• Lada Kalina: 21110-3707010-00, 21110-3707010-01.
• Lada Granta: 21110-3707010-00, 21110-3707010-03.
• Lada Kalina 2: 21110-3707010-00, 21110-3707010-03.

Types of spark plugs... Candles can differ in the number of electrodes: single-electrode (standard), multi-electrode. And also by type: Regular (standard), iridium, platinum. The manufacturer recommends using conventional single-electrode spark plugs for VAZ.

Spark plug life depends on the operating conditions. In accordance with the regulations Maintenance For cars Lada Priora, Kalina and Granta, the spark plugs should be changed every 30,000 km. However, in some cases (for example, when starting the engine in severe frost), new spark plugs can also be damaged by filling them with gasoline. Tip: do not throw out old candles, but use them in such cases.
