The best spark plugs for VAZ 2112 16 valves

To start the engine, spark plugs are an important part that ensures the long-term functioning of the power unit. There is a wide range of spark plugs for VAZ (Lada) cars on sale; choosing the right one for a specific car is not easy. For different types of motor, there is a specific list of parameters recommended by the car manufacturer. To choose one of the best, a car enthusiast is advised to read their descriptions, which are presented in this article.

Which spark plugs are better for VAZ-2112 injector 16 valves

VAZ 2110/2111/2112 cars are the tenth series of domestic cars produced since 1995. Such cars were produced only with gasoline engines (injector and carburetor). Spark plugs for each car of the tenth family come with different part numbers, but in fact they are very similar in size and parameters. The differences in spark plugs on these three cars are due to different engines, although all of them are developed on the basis of a 1.5-liter 8-valve carburetor engine from a dozen.

Which candles to choose

For the VAZ-2112 there are many different brands of spark plugs, which differ in type, composition and appearance. Therefore, what exactly to choose is up to you, and below we will tell you about each of those that are most often chosen by the owners of “two-wheelers.”

JSC ZAZS, Russia AU17DVRM
BERU, Germany 14FR-7DU
CHAMPION, England RC9YC
NGK, Japan BCPR6ES-11
DENSO, Japan Q20TT
BRISK, Czech Republic DR15YC
BOSCH, Germany FR7DCU
FINWHALE, Germany F516

Standard spark plugs that are supplied with all VAZ cars from the factory. Despite the fact that the manufacturer recommends replacing only this model of spark plugs, many car enthusiasts do not share this opinion and use other brands.

BERU 14FR-7DU spark plugs have a special modification in the form of a copper central electrode with a nickel shell. This design increases resistance to wear and corrosion. The conical shape of the skirt allows you to very quickly switch to self-cleaning mode, which has a beneficial effect when traveling short distances in the city. Thanks to the increased spark power, the fuel burns most efficiently to the maximum - and this is already tuning the ignition system and engine.

Champion

Spark plugs from Champion. Made in the EU, Champion RC9YC spark plugs offer low fuel consumption, high stability and increased power at high engine speeds.

Japanese candles NGK BCPR6ES-11 are among the most affordable on the market in the price category.

An engine with such spark plugs runs very stable, and with the throttle valve open to full, it can develop 4.5% more power than with standard spark plugs. When tested on a stand, it shows a result in fuel consumption that is 3.9% less than the “stock” figure.

Denso

Spark plugs from Denso.

DENSO Q20TT has a thin electrode made not from precious metals, which primarily has a beneficial effect on its cost. Thanks to this spark plug shape, the engine experiences a steady increase in power, acceleration and dynamics come to life, as well as a reduction in fuel consumption.

Many owners of the VAZ-2112 note the smoothest and most stable operation of the engine at idle speed.

Brisk

Brisk DR15YC made in the Czech Republic, has a copper core and an extended central electrode insulator. The latter allows it to quickly switch to self-cleaning mode, so this spark plug is well suited for cars operated in urban environments. The interval for replacing spark plugs directly depends on the type and quality of fuel used.

Bosch

Spark plug from Bosch.

Bosch FR7DCU have a copper core in their design, placed in a chromium-nickel shell, which increases the electrode's resistance to corrosion and erosion. Nickel coating prevents sticking of threads and protects the spark plug body from the harmful effects of aggressive environments. The spark plug from this company showed stable, average results in terms of fuel consumption and acceleration dynamics.

Finwhale

Spark plug from FINWHALE.

The body of the Finwhale F516 spark plug is galvanized and made of highly ductile steel, equipped with high electrical insulation, due to which heat, conductivity and mechanical strength are increased due to the high content of aluminum oxide on the insulator. To ensure that the electrodes burn out less, they are made of a nickel alloy.

Causes

The most common of them is the incorrect operation of the car's electronic unit. What’s most interesting is that the spark plugs on the injector are filled more often in winter at subzero temperatures than in summer. And this is not an anomaly. There are objective reasons for this. As the temperature drops, mixing the fuel-air mixture becomes more difficult because a large amount of oxygen requires a large volume of gasoline in cold air. In this regard, the electronic control unit sends a signal to the fuel injectors, thereby increasing the amount of fluid supplied. This is the main reason why the candle floods.

What is happening in the engine at this moment? The injectors supply gasoline to the combustion chamber of the engine, while the starter tries to create the necessary compression in the cylinders, while at the same time trying to produce a spark to generate a flash. At the same time, we should not forget about the quality of our fuel - a lot of impurities and dirt significantly worsen the operation of the injectors, hence the corresponding troubles.

With ideal compression, the spark plugs can easily start even with a minimal impulse, but this only happens on new cars. Therefore, it fills spark plugs on the injector most often on cars more than 3-5 years old.

Spark plugs for VAZ 2110, 2111, 2112 – which ones to put on the injector and carburetor

The spark plugs on the VAZ 2110/2111/2112 have a nickel central electrode, single-pin. For the VAZ 2110 the base engine is an 8-valve carburetor, for the 2111 it is also an 8-valve engine, but with an injector, and for the VAZ 2112 it is a 16-valve, injection engine. But in fact, each car was equipped with all these engines and their modifications. Therefore, spark plugs differ in the context of the 3 main base engines.

On each engine, the spark plugs have different markings, but for an 8-valve engine with an injector and carburetor they are the same and differ only in the size of the gap. Therefore, they can be interchanged by first setting the required gap. For VAZ carburetor engines, it is recommended to set it somewhere within 0.7 mm, but on injectors - 1 mm.

16-valve power units already have spark plugs that are slightly different from the previous ones. Therefore, it is not recommended to install them on 8-valve engines.

The dimensions and article numbers of the original candles are presented in the table below.

vendor code	Engine	Thread / thread length, mm	Key size	Gap, mm	Heat number*	Center electrode material
21080-3707010-86	8 valves, carburetor	M14x1.25 / 19	20.8	0.7	17	Nickel
21110-3707010-86	8 valves, injector	M14x1.25 / 19	20.8	1	17	Nickel
2112-3707010-01	16 valves, injector	M14x1.25 / 19	16	1	17	Nickel

*according to Champion nomenclature

In fact, under the article numbers 21080-3707010-86 and 21110-3707010-86, which go to 8-valve valves, there is the same model of spark plug, only with a different gap. Directly from the manufacturer, it has the article number A17DVRM, the average price is 140 rubles/piece. And under the article number 2112-3707010-01 (for 16 valves) there is a spark plug AU17DVRM, the average price is 200 rubles/piece.

The most commonly used substitutes are listed below. Ten and eleven have the same analogues, only before installation it is recommended to check the gap and, if necessary, set it to the recommended values.

Manufacturer	vendor code	Price, rub (for 1 piece)
For 8 valve engines, injector and carburetor
Bosch	0242235663	100

Denso	Q20PR-U11	115

Prevention

To avoid replacing spark plugs frequently, watch what you put into the tank and avoid “left-handed” gas stations.
Check the condition of the spark plugs regularly, for example, every 5 thousand km. This will save you from excessive fuel consumption and unpleasant surprises on the road, especially in winter.
Buy a set of spark plugs and carry them with you, as they say, just in case.
Monitor the engine oil level and condition.
Buy only high-quality spark plugs, preferably those recommended by the manufacturer of your car, but this does not mean that others are contraindicated for you. You have the right to choose similar spark plugs, the main thing is that they match the parameters (operating temperature, heat rating, number of side electrodes, thread diameter, etc.). Leading manufacturers of spark plugs: NGK, BOSCH, Brisk, DENSO.

Which spark plugs are better for the VAZ-2112 injector 16 valves: survey

Before replacing the spark plugs on their car, most car enthusiasts ask themselves the question, which spark plugs are best to choose? Fortunately, there are many of them in stores. In our article we will tell you in detail how to approach this issue competently, focusing on the choice of the majority of car owners.

The video provides an overview of popular spark plug models for the VAZ-2112:

Let's sum it up

Having tested the five most purchased spark plugs in our country, we come to the conclusion that most options are acceptable if you do not use them for longer than 10-12 thousand kilometers. After passing the mark of 15 thousand kilometers, the spark plugs begin to significantly increase consumption and impair ignition. The engine deteriorates, and you pay more and more money at gas stations and pollute the environment.

And the ride with new spark plugs improves significantly. The engine power increases, and the dips in traction that are common in domestic engines disappear. What brand of candles do you use?

When to change spark plugs on a 16-valve VAZ-2112?

Each spark plug manufacturer has its own schedule for periodically replacing spark plugs. However, the service life of 20-30 thousand kilometers for cars of the VAZ family is generally similar. However, if any interruptions occur during engine operation, as well as other reasons why it is necessary to replace the spark plugs, it is recommended not to delay and carry them out.

After carefully reading this article, you can easily choose the candles that are right for you, based on your needs, capabilities and purpose.

Checking relays and ECUs and other sensors

It may be necessary to remove the fuel pump to check. You will need to remove the rear seat and check the voltage at the pump terminals. The device should show + 12 volts. Then crank the engine using the starter. When it is triggered, they proceed to subsequent actions. It may happen that when you turn the ignition key, the starter does not turn. Then you need to check the reliability of all wires on it. The cause may be a problem in the contact group in the ignition switch.
If it is determined that everything is in order, check the spark on the spark plugs. To do this you will need to open the hood. First, you need to unscrew the spark plug from the first cylinder. It is necessary to throw an armored wire over it and press it against the mass. In this case, the candle must be held with pliers and not with your hands. Otherwise you will get an electric shock. At this time, the assistant starts the engine. All other candles are checked in the same way. If there is a spark on each cylinder, it is necessary to look for ignition problems.
The situations may be different, for example, a spark is present on cylinders 1 and 4, but not on cylinders 2 and 3. The ignition module should be replaced. If the replacement does not give a positive result, you should look for the reason in the output transistor switches to the ignition module from the ECU. The ECU may need to be repaired.
It may happen that there is no spark on any cylinder. VAZ 2110 does not start because there is no spark. Often the reason for this lies in the crankshaft position sensor. The DPKV ECU gives a signal through which pulses are sent to the ignition module so that a spark is formed. The cause of the malfunction may be the lack of connection between the gear and the generator wheel. This can occur even if the DPKV is in full working order. At the same time, the crankshaft rotates, but the sensor will not process these rotations. Many are frightened by the fact that the VAZ 2110 injector has a large number of sensors. Indeed, there are a lot of them, but the reason that the VAZ 2110 does not start the first time is only one thing - the DPKV sensor is faulty.
It is necessary to unscrew the spark plug from the cylinder and check its moisture content. A dry spark plug indicates that the injector is not spraying fuel. Then check the pressure in the fuel rail. It has a special bolt on the side. It must be unscrewed and a pressure gauge inserted in its place. It will show the presence or absence of pressure in the ramp. But it may not be at hand. Then the bolt is unscrewed and the pump starts. If there is pressure in the ramp, a good stream will flow out of the hole.
If there is no pressure, the fuel filter must be replaced. The reason may also be that the line on the way from the fuel tank to the ramp is clogged. If the unscrewed candle turns out to be wet, then they all need to be unscrewed, wiped and dried thoroughly.
Sometimes the reason is that the injectors are clogged and need to be cleaned. Clogged injectors may cause the spark plugs to be flooded with fuel. Dirty injectors are often the reason why a car engine has difficulty starting.
Sometimes the reasons that the VAZ 2110 16 valves does not start may be of a deeper nature. They are very difficult to diagnose. But for the VAZ 2110 this is the exception rather than the rule.

Spark plugs for VAZ (Lada) 2110/2111/2112

for repair of VAZ (Lada) 2110/2111/2112

I bought candles from what I had. In the end I bought Finwhale and changed it myself without any problems. At first glance, everything was fine, the car was driving normally, but after 5000 km, the engine began to misfire. I immediately suspected the candles and decided to install the original. On the original, all the problems disappeared. As a result, Finwhale candles have a very low service life and quality.

They recommended good Finwhale candles at a reasonable price, I bought them, installed them, they really weren’t bad. The car starts better and is more playful. So if someone is looking at purchasing, I can confidently recommend Finwhale.

I am not a fan of the A17DVRM, now there are no burrs on the side, the spark plugs are made neatly, in appearance they cannot be distinguished from Bosch. But the fact that they don’t run much is a fact, the central electrode of the “semnashki” feels like it’s made of real copper, it burns out quickly, on machines with HBO this is especially noticeable, the same NLCs live several times longer.

I took NGK spark plugs - the ceramic insulator burst on one spark plug, the mileage was comical.

I tried changing BOSCH, BOSCH itriut, FINVAL spark plugs, but on NGK the effect is less pronounced.

Selection options

Used and new spark plug for internal combustion engines
Which spark plugs are best for VAZ?

To select good SZ, you must be guided by the following criteria:

The first parameter to consider when purchasing is the heat rating. It should be noted that this parameter is conditional and not universal, so it must be selected in accordance with the model of a particular motor. This number shows the pressure level in the internal combustion engine cylinder at which glow ignition occurs. The use of SZ with a higher heat number is allowed, but is not prohibited if it is lower.
Another parameter is the possibility of self-cleaning. Unfortunately, this parameter can only be accurately verified in practice, since all SZ manufacturers promise consumers a high level of self-cleaning. If this indicator is really high, then carbon deposits will not form on the SZ, which is especially important for their optimal operation.
When buying spark plugs from a VAZ, you also need to take into account their gap. Each manufacturer sets the appropriate gap for individual product lines. If we are talking about domestically produced cars, then in this case this gap on the VAZ spark plugs should be 0.5-0.7 mm.
Traditional SZ are equipped with two electrodes - one central and one side, but not so long ago global manufacturers began producing devices with 3 and 4 electrodes. These electrodes cannot produce multiple sparks - their purpose is to provide more consistent sparking. Accordingly, the use of such SZ contributes to more stable operation of the power unit due to improved ignition procedures.
Before purchasing SZ, carefully inspect them for mechanical damage. If you see that there are cracks on the device’s body, then it is better to refuse to purchase such SZ. Also, before installation, check that the gap is the correct size.
To diagnose purchased SZ, you can install them in a pressure chamber, of course, if you have such an opportunity, then adjust the pressure in it to about 10 kg/cm2, and the current should be connected with a value of 22 kV. As a result, a spark should begin to form. If the spark appears intermittently, this indicates that the SZ is not working, but if the sparking is continuous, then the devices can be purchased (the author of the video is Nail Poroshin).

How to choose the right spark plugs for a VAZ

When choosing the best spark plugs for a VAZ engine, you should be guided by the parameters of the car and engine:

Heat number. If a spark plug is approved for use on a specific car, then it will be suitable in terms of its thermal characteristics. Small deviations play a seasonal role and depend on the owner’s driving style.
Geometric dimensions - diameter and thread pitch, length of the threaded part of the body. Protrusion or recession of the electrode area into the material of the block head is not allowed.
The nominal gap between the electrodes can be adjusted. The spark plug will operate uninterruptedly at the factory-set value.
The wrench size is of secondary importance and affects the applicability of the existing tool. It is always safer to choose the size that matches the factory size.
The sticking out of the electrodes has an indirect effect; the heat rating depends on it.

Symptoms of a problem

If the spark plugs fail, there will be no spark. Consequently, the fuel mixture will not be able to ignite, the engine will freeze and show no signs of life.

There are several telltale signs that may indicate poor spark plug performance.

The engine starting procedure gets worse. The starter turns, but the motor itself does not respond;
Fuel consumption increases;
CO emissions increase;
At idle and while driving, the engine begins to jerk the car;
The dynamic performance of the car drops, it is not possible to raise the speed to the required maximum, the engine power noticeably decreases, etc.

But all these are indirect reasons, since they do not directly indicate the failure of the spark plugs. You can verify their malfunction only by checking.

Rating of the TOP 5 best spark plugs for VAZ cars

Copper-nickel spark plugs for VAZ cars of the “Standard” category are used on carburetor engines with a contact ignition system; their reliable service life does not exceed 10,000 kilometers.

Attention! These are products with a good reputation, so they are massively counterfeited. The rules for identifying the original can be found on the manufacturers’ websites.

TOP	Candlestick pattern	Installed gap, mm	Thread diameter, mm	Length of threaded part, mm	Key size, mm	Order code	Price per piece, rubles, wholesale/retail

NGK 7529 BP6E

The spark plugs are universal and work across the entire range of temperatures and loads. They are resistant to the formation of deposits on the insulator, maintain the shape of the electrodes and the size of the gap. V-line technology ensures uninterrupted sparking. The copper rod in the central electrode removes heat, preventing overheating and damage to the insulator. The sealing of the housing is adequately done, the tightness is always at its best.

The gap for these spark plugs is 0.9 mm. This means that it is better not to use the product for a carburetor engine, only an injector.

The price for such quality is attractive and does not go out of the general range in the category.

The cost of candles is, on average, 150 rubles per piece.

Advantages and disadvantages

Good engine starting in any weather. Sparking without interruption due to the use of new technology. Excellent tightness. Compliance price/quality.

There are often fakes on the market

BRISK Classic L15Y

A characteristic feature of the Classic L15Y model is the ability to operate at reduced secondary voltage energy, which is suitable for older VAZ cars. A slightly lower heat rating and a small gap allow you to confidently start the engine at sub-zero temperatures; the spark plug warms up quickly and is not prone to sparking and carbon deposits.

However, because of this, the products may fail under loads and high temperatures, but for low-powered classic VAZ engines this will not be a discouraging factor. The service life is average in the class of budget candles based on copper and nickel.

The cost in the store is about 80 rubles per piece.

DENSO 3043 W20EP-U

The best candles for this application took first place in the ranking. Experienced car service workers always recommend Denso products, knowing that the client will be satisfied. There will be no complaints about the candles; the products guarantee their operation regardless of the mode - idle or load.

There are some downsides - the U-Groove technology does not prevent you from driving on a cold engine at low speeds, soot formation is possible, the spark plugs are a little colder in heat rating than inexperienced drivers would like.

The gap on the product is 0.8 mm, therefore, it is not suitable for a carburetor engine.

The cost, on average, is 130 rubles per unit.

Advantages and disadvantages

Excellent quality, which is why spark plugs are installed on many cars from the factory. Copper core ensures reliability. Increased flame spread thanks to the U-shaped groove of the side electrode.

Soot quickly forms on candles.
