Which spark plugs are better for VAZ 2131 injector 8 valves


What do candles do?

As you know, a spark plug supplies a spark to the cylinder to ignite the fuel inside the combustion chamber. The spark plug is exposed to enormous temperatures, which of course does not have a favorable effect on its condition, so neglecting to replace spark plugs is highly discouraged and, if possible, it is advisable to change them before winter for easier starting in cold weather.

A worn-out spark plug can cause a lot of trouble, such as a lot of engine tripping, a number of misfires, loss of power and even an increase in fuel consumption.

In this article you will find the answer to the question of which spark plugs are best suitable for the Lada Niva.

Recommendations for replacement

Before you start replacing VAZ 2106 spark plugs, you need to make sure that the gap between the electrodes in the new parts is 0.7-0.8 mm for cam ignition systems and 0.8-0.9 mm for electronic ones. The gap is measured with a flat feeler gauge; in spark plugs with several side electrodes - with a round one.

The replacement algorithm is as follows:

  1. Turn off the ignition and remove the high-voltage wires from the spark plugs, holding them by the tips.
  2. Unscrew the old parts and clean the seats with a brush.
  3. Screw in new spark plugs, tighten them with medium force.
  4. Connect the wires and start the engine.

When connecting high-voltage wires, it is important not to mix them up, so you need to follow the markings on the distributor cover.

Spark plug gap on Niva

The gap between the electrodes on the spark plugs is one of the main indicators that directly affects the operation of this engine part. It must be checked every 20-25 thousand km to ensure proper engine operation. The gap can be adjusted if it is out of the normal range or it is better to replace the spark plugs with new ones.

The normal gap on Niva spark plugs is 1.1-1.2 mm.

Niva's original spark plugs

The Niva is supplied from the factory with domestic spark plugs from the Engel plant, which specializes in the production of automotive spark plugs. The plant installs AU17DVRM brand spark plugs; these plugs have proven themselves well and meet all quality standards and service life.

A large number of analogues of these spark plugs have appeared on the market, which are no worse than factory ones, and sometimes even better. Analogues of candles can be both imported and domestic.

Below is a table of spark plugs suitable for a Niva car from well-known brands such as DENSO, BOSCH and Brisk.

The best candles for Niva

Based on reviews from forums, it has been repeatedly revealed that Nivovody gives their preference to NGK candles. These spark plugs are excellent for the Niva engine and can withstand high temperature loads. NGK spark plugs make it easier to start the engine in cold weather and even reduce fuel consumption due to their structure. The closest to standard spark plugs and suitable in design to the Niva engine will be NGK No. 11 spark plugs.

These spark plugs easily overcome the 30,000 km barrier without any damage.

Which spark plugs for VAZ are better to choose?

There are a large number of different modifications of the part, which complicates life for motorists. The problem is that each motor is designed for a specific type of spark plug. If you supply the wrong part, a number of negative consequences can arise.

  1. Misfire of the mixture due to the gap between the electrodes of the element being too wide.
  2. Interruptions in the operation of the internal combustion engine caused by too low spark power.
  3. Instant failure of the device due to too much electrode protrusion.

Also, depending on the inconsistencies present, other malfunctions may “pop up” that reduce the comfort of using the car.

What to look for when choosing.

Specialists from the AvtoVAZ plant recommend selecting spark plugs according to a number of parameters.

  1. Heat number. The parameter characterizes the rate of heat removal from the working part of the candle. At the same time, the electrode transfers excess heat to the spark plug skirt in a timely manner, which ensures stable operation of the part. If energy is removed too quickly, scale forms on the working part of the part, which prevents normal spark breakdown. If the withdrawal is too slow, the thin electrode overheats. The process provokes the formation of glow ignition. This prevents the engine from operating normally due to detonation of the mixture or its early ignition. Under normal thermal conditions, a spark adequately breaks through the spark plugs and does not form excessive carbon deposits.
  2. Spark gap. Some users know that for the engine to operate correctly, the spark gap on the spark plugs must be maintained. The working gap on VAZ spark plugs is strictly set by the manufacturer of the power plant and is necessary due to the fact that the formed electric arc has a certain strength. As the distance increases, the spark loses stability, which can lead to misfires. In the opposite case, easier starting of the engine is ensured, but when the gas is released, the electric arc current may not be enough. This is justified by the fact that each ignition coil has a certain transformation ratio, usually equal to 2000 units. This means that during the start-up of the internal combustion engine, the elements produce up to 14 kW, and during normal operation it is already 24. Consequently, failure to comply with this parameter can lead to serious disruptions in the operation of the motor.
  3. Departure of the working part of the electrodes. The parameter is critical for adequate operation of the power plant. The spark plugs on the VAZ 8-valve injector, as well as for carburetor models, have electrodes strongly pushed forward. This is due to the fact that the structural parts are located in the corner of the combustion chamber, where there is no adequate ventilation. The overhang of the working part allows for better ignition of the mixture and stabilizes engine operation. If the spark plugs are mounted in a multi-valve engine, where the inserts are located in the center of the valve head, it is recommended to install spark plugs with a deep-set core - this will prevent damage to the electrodes by the piston bottom and an abundance of carbon deposits on the structural elements.
  4. Number of electrodes. Initially, manufacturers position this parameter as a definite plus. When one electrode “burns out,” the spark plug switches to another, which significantly increases its service life. However, not everything is as simple as it seems at first glance. If the mixture is sprayed unevenly in the cylinder (poor ventilation of the combustion chamber), and at this moment the spark jumps to the shadowed part (the place where the exhaust remains), misfire may occur, which will lead to unstable operation of the power plant. Additionally, this fact increases the wear of the catalyst and engine oil, which is critical for VAZ cars.
  5. Manufacturer. The manufacturer of the product is also an important parameter. Users recommend buying from trusted brands that have been on the market for a long time. The cost of such candles will be significant, but with proper selection and operation they will work for a long time and without significant complaints.

Spark plugs for Chevrolet Niva and Niva

The topic of this review is Chevrolet Niva and Niva spark plugs, using the example of the German manufacturer Bosch. There are similar lines from other manufacturers, but since I am currently working with this manufacturer, I will tell you using the example of its products.

spark plugs for the Niva family

  1. Spark plugs for carburetor cars. The factory gap between the electrodes is 0.7 mm. I will not describe all the marketing gimmicks that the manufacturer writes, just high-quality spark plugs that maintain their required engine hours. Frequently asked question: the contact ignition system has been replaced. A distributor with a hall sensor, a switch and a coil from 2108 are installed. What spark plugs should I use? I experimented with this issue several times. I decided for myself: regular carburetor spark plugs with a slightly increased gap, literally by 0.1-0.2 mm. Produced in Germany.
  2. Spark plugs recommended by the manufacturer for 8 valve injectors, including for the Niva-Shniva family. The established gap between the electrodes is 1.1 mm. In the case of these candles, it would be fairer to say “workhorse”. Nothing outstanding, but they work until either diesel fuel is poured into the tank, or the gap increases to 1.5 mm. Bosch located the production of these candles in Russia, which, unlike other manufacturers, had a very positive effect on the price.
  3. A spark plug with a central electrode coated with platinum. Named . I’ll dispel the common myth that you install “platinum” or “iridium” spark plugs and the horn will fly like an airplane. The main advantage of these candles is their RESOURCE. When you install ordinary spark plugs, after 10-15 thousand the gap between the electrodes “goes away” due to the “knocking out” of the central electrode by a spark. According to my observations, with good gasoline, “platinum” spark plugs, without deteriorating their parameters, have a resource of more than 50 thousand km. Produced in Germany.
  4. Multi-contact spark plugs. In this case, four-pin. For a long time I could not clearly explain to clients what the “raisin” of the issue was. I will not repeat the nonsense that is said in stores and markets. The answer came when a batch of candles was sent to Yakutsk, to the same “junior-experimenter” like myself. It was a completely different SUV, but then this was confirmed in our cars. Their main advantage is starting the engine in the morning in very cold conditions. This has led to some of my clients installing "seasonal" candles on their cars. In summer they are ordinary, in winter they are multi-contact. Candles are made in Germany.

Spark plugs Niva Chevrolet and Niva. Correct installation

Several general questions that Papuan services either “forget” or never knew about. The tightening torque must correspond to that specified by the manufacturer. The metal sealing ring should not turn into foil when tightened, otherwise it will cease to perform its function. It is advisable to install the spark plug with copper, aluminum or ceramic lubricant, especially in our case when we have an aluminum cylinder head.

There is no need to pour lubricant as much as you can; one drop on the threaded part is enough so that next time the spark plug does not “stick” and can be easily unscrewed. Now about gasoline and spark plug life. Don’t think that if you installed a new set, you will run on the spark plugs until they die naturally. ONE “left” filling is enough so that a set of candles can be thrown into the trash. And of course the quality of gasoline itself.

In St. Petersburg we have a network of “red-colored” gas stations; it happens that a couple of gas stations are enough for the spark plug to turn red; naturally, this “pattern” cannot be penetrated by any spark, leading to the breakdown of the ignition module.

Manufacturers

A little about the manufacturers. I can name several companies that produce spark plugs for Chevrolet Niva and Niva. These are Champion, Eyquem, Beru, Denso, Valeo, NGK. A few words about NGK. I used the products of this manufacturer for a long time until “small” problems began. A new set of spark plugs was installed on the car, and after a couple of thousand, one spark plug would “fly out” and the engines would start to stall. So I bring candles not only for myself, but also for several diagnostic companies, statistics have appeared, this phenomenon has become common. Without being lazy, I sent several sets to the Moscow representative office.

They diplomatically answered me: I’m a fool, the candles are tightened with the wrong tightening torque. Well, they sent it nicely)) Having waited until NGK held a seminar in Russia, I went and laid out everything to the “real Japanese”. Having made a thousand Japanese apologies, in a private conversation, he said that for the sake of competitive prices, the production of the cheap segment of candles was transferred to other factories. But the percentage of defects is within normal limits and sellers and services need not worry. And if something happens, then send the defect to the representative office for examination. The circle is closed.

Since 2011, I began working with products from German manufacturers Bosch and Beru.

LADA spark plugs: top 10 options

The rating contains 10 modifications of spark plugs, without division into specific car models.

10th place: ZZ A17 DVRM

The list of the best offers opens with an effective model that is in demand among a large number of buyers. Such prevalence is ensured by the stable quality of products. In the original packaging it is impossible to find a defective part or a spark plug with a broken gap. A significant advantage of the products is the ability to work actively even when the voltage drops to 6V in the on-board network. Similar spark plugs in the VAZ 2107 are often found due to their moderate cost.

The indicators are overshadowed by bad statistics - as of 2020, 35% of the kits on the market are fakes, which forces motorists to carefully select products in stores.

  • reasonable price;
  • durable;
  • simple design.

9th place: TZ 17 DVRM

The next representative of the rating implies the presence of as many as three electrodes on the working part of the device. A large number of motorists install such spark plugs on a VAZ carburetor or even an injection type. Thanks to the use of advanced developments in design, the manufacturer has increased the service life of the electrode.

Pirate copies also play a role here - there are a large number of them, which makes buyers cautious about purchasing products.

  • good performance;
  • long period of operation;
  • wide use.

8th place: DENSO W20EPR-U11

If you want to buy VAZ injector spark plugs, you can turn to the eighth position of the rating. Candles represent a compromise between high quality and moderate cost. Thanks to this symbiosis, such spark plugs are perfect for the VAZ 2106. Also, this model will be relevant for more modern versions. It uses technology to increase spark stability. The development significantly increases the service life of the part, which helps save on vehicle servicing. This also made it possible to reduce the maximum voltage drop to 6.5 V, which is less than that of Russian analogues, but thanks to stability, the spark plugs win positions.

  • stable operation during voltage fluctuations in the on-board network;
  • long service life.

7th place: BRISK LR15YCY-1

The next contender for the title of best is distinguished by an increased overhang of the working part. The specified spark plugs for the VAZ 2107 carburetor are ideal. The standard eight-valve engine works great with the included model.

In terms of performance parameters, the model is a confident average and can be used even on used foreign cars with similar engines. The ability to work on a dead battery has also been developed. The product is capable of igniting the mixture even at 6.2 V within the network, which is significantly better than the performance of competitors’ analogues. Buyers consider the rather high cost to be the only serious disadvantage.

  • increased resource;
  • sufficient versatility;
  • The gap fits well with classic engines.
  • high price;
  • difficult to find - not very common.

6th place: NGK BPR6 ES-11

The specified spark plugs for the Lada Granta are quite suitable. The model stands out among its competitors because it is manufactured in France. European quality did not suffer even with a fairly successful attempt to reduce the cost of products. The design and appearance of the part leaves much to be desired. Here you can find an unevenly soldered electrode or a damaged manufacturer’s logo.

We choose spark plugs consciously

All products from the DENSO IRIDIUM POWER series have proven themselves well. For the “2123” motor, one option is suitable, IW20, but IK20 is already a turnkey “16”. The cost of the kit can exceed 90 euros. Do we need it?

On the left is a BOSCH SUPER 4 spark plug.

Those who bought spark plugs with four electrodes are happy. We are talking about the BOSCH SUPER 4 series and the WR78X version. But here, again, you will have to overpay. And that’s why they often choose NGK products. We are talking about the V-line line and option number 13. We need V-line 13 BPR6ES-11 spark plugs. Their service life in the “2123” engine can reach up to 60 thousand.

V-line 13 kit

Brand "NGK" for Niva Chevrolet

Up to 90% of all NGK products are produced in Japan. And approximately 9% are products of the French branch. There are NGK factories in 14 other countries. Well, spark plugs for VAZ cars should be produced in France - the factory is located in the suburbs of Orleans.

The box usually has a barcode on it, so V-line candles, as it turns out, are made in Holland. The country code is 087.
