The line of cars from VAZ - Priora, Kalina and Granta are similar in many ways. Each of these cars has different modifications with different engines. But, in fact, the main difference in the engines of these models is only in the number of valves.

Spark plugs for Priora, Kalina and Grant differ only depending on whether an 8- or 16-valve engine is installed, regardless of the generation or year of manufacture of the car. Original spare parts for all three models are supplied by the Russian company ZAZS OJSC.

How often should you change spark plugs?

The standard frequency of replacing spark plugs on a VAZ can vary quite widely - from 30 thousand kilometers for regular (standard) ones and up to 80 thousand for modern iridium and platinum ones. As with any other consumables, fluctuations are possible, the main factors influencing which are the condition of the engine and ignition system, the quality of the fuel and the nature of the vehicle's operation. For example, if you often drive short distances around the city, then even if all car systems are working normally, the spark plugs usually become covered with black soot quite quickly, since they do not reach the required temperature for self-cleaning.

It is not difficult to diagnose the condition of spark plugs. It's better to do this visually. If you find only slight darkening and a small grayish-yellow or pale brown coating on dry electrodes that have not lost their shape, you can safely return the spark plugs to their place and drive on.

If a significant coating of black or white or a shade of rust is detected, oiling is already a reason to think about replacing them or at least cleaning them. Cleaning can be done by soaking the spark plugs in gasoline or a special liquid and carefully removing the deposits with a brush or fine sandpaper. In this case, be sure to check the spark plug gap between the electrodes using feeler gauges. It will almost certainly be different from the recommended 1-1.1 mm. To continue operation, it must be restored by carefully bending the side electrode. But keep in mind that this is more of a temporary measure, after which the period for replacing spark plugs will pass much faster than with new ones.

It is better to throw away electrodes if they:

• Heavily contaminated
• Lost form
• Melted
• Broken off
• Has damage to the insulator

By the way, this condition is usually a direct indication of the presence of more serious problems, or the car owner’s reluctance to carry out maintenance on time. Like all other consumables, it is better to change candles regularly and in a timely manner. But what are the best spark plugs for Kalina?

How to set the gap between spark plug electrodes

It has been proven that an ideal spark plug electrode gap can ensure quick start of the power unit and maintain its power parameters and optimal fuel costs. Their increase is promoted by untimely combustion of the mixture.

Adjustment of the electrode intervals should be carried out using a special wrench for unscrewing and a probe set:

• We free the cylinders from the spark plugs. We measure the interval of the central and side electrodes. We remember that the contact system corresponds to a gap of 0.5-0.6 mm, the electronic one - up to 0.8 mm. For Lada Granta, the recommended gap is from 1 to 1.15 mm.
• If you have this data, you should select a probe with the required thickness and insert it between the electrodes.
• If necessary, adjust the parameters by bending/bending the electrode located on the side.
• This procedure must be applied to the remaining candles. After this, install it back into the cylinder bores.

A similar procedure of manipulations is performed in the case of adjusting the electrode gaps in GAZ cars.

What candles to put in Kalina

The manufacturer for Kalina recommends domestic spark plugs of type A17DVRM (for 8-valve engines) and AU15DVRM, AU17DVRM (for 16-valve engines), as well as their foreign analogues. For example, for 8-valve cars, spark plugs BRISK LR15YC (Czech Republic), BOSCH WR7DC (Germany), NGK BPR6ES (Japan) are suitable, for 16-valve cars, respectively, BRISK DR15YC, BOSCH FR7DCU and NGK BCPR6ES.

All of the above spark plugs are single-electrode – this is the type again recommended by the manufacturer. It is not prohibited to install multi-electrode analogues (it is believed that they give a better arc), just keep in mind that they will cost a little more, and you may not notice the effect. As for iridium and platinum spark plugs, their main advantage is their long service life.

How to get rid of unnecessary details

Any 16-valve engine has a plastic protection installed on top. But the protective cover can always be removed by simply pulling the part up. By the way, the rubber supports on the covers of motors 21126 and 21127 will be the same (see figure).

It is recommended to unscrew the filler plug, but you can leave it in place. The lid must be pulled up, snapping off the supports one by one.

Everything looks more complicated than it actually turns out to be. Try it!

Actions before replacement

First of all, we recommend disconnecting the negative terminal of the battery. To do this you need a key “10”. Then disconnect the ignition coil connectors. The appearance of one connector is shown below.

By pressing the latch, the connector is pulled up

Next, taking a TORX E-8 wrench, unscrew the screw securing the coil.

Need a TORX spanner

The coil itself can be pulled out by holding it by the connector body.

The connector will not break, try it

Finally, the engine is ready to replace the spark plugs. This process is discussed further.

Do not allow dust to get into the spark plug well! If necessary, you can use a can of compressed air.

Replacing spark plugs: when to change spark plugs and after how long?

The issue of replacing spark plugs, as well as the frequency of this procedure, is as controversial as the question of which motor oil is better or which tires are best to buy for the summer.
As with any question, the first step is to consult the instruction manual. It, as they say, indicates in black and white the interval after which the spark plugs should be replaced. Moreover, the same manual will indicate the manufacturer and brand of the spark plugs themselves, which are recommended to be installed. It would seem that the problem has been solved, the answer to the question has been found, the article can be finished! However, in reality everything is far from so simple.

Well, firstly, the manufacturer, as we know, does not always indicate in the manual what is really best for our car. There may be many reasons for this, I will not list them, I will say one thing that the main one is the financial benefit of the automaker itself, which has entered into a contract with this particular spark plug manufacturer. Moreover, time passes, new, more advanced products appear, and it is not at all necessary to install old-style candles on your machine, which are obsolete and may have already been discontinued.

Criteria for selecting candles

Experts recommend not buying spark plugs yourself if you do not understand this issue and also do not know the temperature conditions of your engine. In this case, it is better to consult a specialist from an auto repair center. He will help you choose a suitable part that will not only serve correctly, but also will not require constant repair or replacement.

As we have already said, with careful use, the spark plugs can not be changed for 3 years. That is why there is no need to save on these devices, otherwise after a short time you will have to spend money again on buying new candles. Do not hesitate to seek competent help, as it is better to get advice and buy a quality part than to take what is offered in the store and then regret your choice. In any case, service life depends on the conditions of use. It is advisable to change spark plugs every 30 thousand km.

How long does it take to change spark plugs?

• If the car is new, it is recommended to change the spark plugs during regular maintenance at the dealer, after 10 thousand km, this will ensure proper engine running-in and smooth operation.
• If the car has significant mileage, but you care about how much the engine consumes per 100 km, how it works and how your car accelerates, then it is better to change the spark plugs after 20-30 thousand km. mileage, provided that the candles themselves are able to cover this mileage. If the spark plugs are of high quality, then most likely they will be able to run for 30 thousand.
• If the car is used regularly, the operating conditions are not the best, and the fuel is either bad or very bad, it is better to change the spark plugs more often, for example, every 10-15 thousand km. Moreover, taking into account all the above arguments, it is also recommended to replace the fuel filter more often.

Many people who “understand” the issue of spark plugs, and cars in general, are now probably nervously grimacing and complaining, saying, why change them if the engine already works like a clock? There are some, right? So, indeed, some spark plugs and motors are truly capable of demonstrating iron endurance, but only SOME . Are you sure that your engine or spark plugs are exactly like this? Is not a fact! The fact is that it is not so easy to notice even a slightly increased “eating” of fuel, and if the BC does not yet show consumption, then it is completely impossible. Perhaps for some this “insignificant” does not play any role, but if you add up +1-3 liters for every hundred mileage. If this doesn’t scare you, then calculate how much you will overpay per 1,000 or 10,000 km. As for me, taking into account fuel prices, the figure will be an impressive one, so, whatever one may say, it will be cheaper to replace the spark plugs ahead of schedule. This way, you will save money and enjoy the engine, which in turn will not fail at the most inopportune moment.

Possible breakdowns and their causes

There are many reasons why spark plugs can fail. This can happen due to contamination with oil or carbon deposits, destruction of the insulator, mechanical damage, rupture of the jumper, etc. Realistically, you can only deal with pollution. In all other cases, you will have to think about replacing the part.

There are three main cleaning methods: boiling method, sandblasting method and ultrasonic cleaning method. Due to the fact that ultrasonic cleaning requires specialized equipment, we will focus on the two remaining methods.

Digestion method

The essence of this method is that you need to boil the candles in water with washing powder for an hour. This method will allow you to clean the part from dirt without damaging the housing. It is worth noting that after cleaning they produce an unstable yellow spark, which can cause problems at high speeds.

Sandblasting method

The part is cleaned with compressed air supplied from a sandblasting machine. Unlike the first method, after such cleaning the candles completely restore their original parameters and give a good blue spark. However, this method only works with single-electrode ones, since the ceramic cone is more accessible in them than in multi-electrode ones.

Since my Kalina’s mileage has long exceeded 30,000 km, I decided to replace the factory spark plugs with new ones, although, to be honest, the factory ones still felt fine. In cold weather it started up to -20 the first time, and if the thermometer dropped even lower, then the second time. At idle, of course, the tachometer needle floated a little, but it was barely noticeable to the eye. In short, we could still drive, but since it is written in the Murzilka - change it after 30,000 km, then we will follow its instructions and recommendations.

It didn’t take long to choose a company, since most car owners speak quite well about NGK spark plugs, and the main thing here is not to run into a fake. If you have a 16-valve Lada Kalina, then you need to take NGK No. 11, and if you have a regular 8-valve engine, then No. 13. I’ll describe the whole procedure a little, maybe this information will be useful for girls or beginners.

Prevention

1. To avoid replacing spark plugs frequently, watch what you put into the tank and avoid “left-handed” gas stations.
2. 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.
3. Buy a set of spark plugs and carry them with you, as they say, just in case.
4. Monitor the engine oil level and condition.
5. 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.

I have everything, I hope you will draw the right conclusions. Those who liked the article can express their gratitude in the comments. Those who didn't like it can also express disagreement.

When installing the spark plug, you must screw it in by hand to avoid damaging the threads of the spark plug hole in the cylinder head.

If the spark plug does not follow the thread, strong resistance to rotation will be felt. In this case, it is necessary to completely unscrew the spark plug and, after cleaning the threads, re-tighten it.

Finally tighten the spark plug to a torque of 31–39 N. m.

Attention! Over-tightening the spark plugs can damage the threads in the spark plug holes in the cylinder head.

The official resource of candles is 30 thousand kilometers. In my Kalina, until I was thirty, they did not betray themselves in any way, they worked like clockwork. Never even unscrewed it. I talked to the fret workers - they told me that 30 is not the limit for candles. They easily work 1.5-2 times more. So I decided at TO-30 thousand that I would not change them, let them work. I'll change it when the sparking stops.

The candles successfully survived their legal 30 thousand... but did not even reach the 31st. In mid-January, at 30,700 km on the way to Chelyabinsk, while accelerating, the “Check engine” light suddenly begins to blink, the dynamics suddenly disappeared, the engine stalled. At the same time, the car could still reach its 110, I must say. I stopped, restarted the engine, the error disappeared, the engine was normal. But then 8 more times on this trip, until I returned home, this error popped up! You restart, drive - and then again. I didn’t immediately realize that the self-diagnosis system detects missed flashes and thereby notifies about the problem. In general, the end of the candles has come. And you can’t blame it on the fuel - the error occurred when the tank was almost empty and was running on a light bulb.

After driving for a few more days, restarting the engine many more times, I realized that the problem would not go away, although at some moments it seemed that everything was already gone. I bought a set of the same factory new spark plugs AU17DVRM from a dealer for 300 rubles and changed them in the evening in about 20 minutes. Initially I wanted to buy NGK proven spark plugs, but didn’t get to the store.

AVTOVAZ instructions for replacing spark plugs and coils on a VAZ engine

According to the regulations, replacement of spark plugs on VAZ engines of front-wheel drive LADA cars is provided every 30 thousand km. mileage How to replace spark plugs and individual ignition coils (IIC) with your own hands is described in the factory’s technological instructions.

1. Unscrew bolts 4, Figure 5, and disconnect ignition coils 5 from spark plugs 6 (replaceable Torx E8 head, wrench).

2. Remove the spark plugs (spark plug key 16).

1. Install spark plugs 6, Figure 5, and tighten with a torque of 20…30 N∙m (2.0…3.0 kgf∙m) (replaceable high head 16, extension, wrench, torque wrench).

2. Before installing the ignition coils, apply lubricant type NIINP-233 TU 38.101687 1 mm thick to the inner surface of the rubber seal of the spark plug. The consumption rate is 1 g per engine.

3. Install ignition coils 5, tighten with fastening bolts. The tightening torque of the ignition coil mounting bolt is 4…8 N∙m (0.4…0.8 kgf∙m) (replaceable Torx E8 head, extension, wrench, torque wrench).

How to tighten a spark plug with the required torque without a torque wrench

experts from the magazine “Behind the Wheel” said:

1. Tighten the spark plug by hand until the washer touches the wall.

2. Tighten the new spark plug by 200-220 degrees or tighten the previously installed spark plug (the ring is already crimped) by about 30 degrees.

Step by step replacement

1. First, disconnect the negative terminal of the battery. Ten key nut.

2. Remove the engine protective cover. We just pull it towards ourselves.

3. Using a socket head, unscrew the fastenings of the ignition coils. Each coil is secured with one bolt.

Ignition coil bolt locations.

4. Remove the power connectors from the coils. On the connector, press the latch with your thumb and pull it towards you.

5. Take out the coils. They fit tightly, so you need to apply some force.

We stack the coils so that we remember where each one was. During assembly you need to install it as it was.

6. Unscrew and change the spark plugs. I advise you to change one spark plug at a time. That is, they unscrewed one spark plug and screwed in a new one.

If you unscrew all the spark plugs at once, there is a chance that debris will get into the wells.

We tighten the candles without fanaticism.

7. Insert the coils all the way and tighten them with bolts.

8. Connect the connectors and battery terminal.

There are four grooves on the cover, and four matching holes on the motor. Just put the grooves into the holes and press.

How often should you change spark plugs on a Lada Kalina?

Replacing spark plugs on a Lada Kalina is a very simple and not too expensive procedure. However, it is not always necessary to replace consumables; it is quite possible that the old spark plugs will serve you a little longer.

When to replace

Recognizing wear or malfunction of spark plugs is quite simple; you need to carefully observe your car and notice signs such as:

• Fuel consumption has increased several times over the last week and month, but the car itself shows no signs of breakdowns;
• The car does not start after the first attempt, you have to try hard to get it to go;
• And if problems arise when gaining speed.

The catch may be the fact that such “symptoms” may indicate malfunctions of the spark plugs and other systems of the car - the gas pump, fuel supply, air filter or even the exhaust system.

Which spark plugs are best for an 8-valve Kalina

AvtoVAZ recommends several options for spark plugs.

A17DVRM - original number. A27DFID is a more modern analogue, and according to reviews it is better. The cold start problem goes away.

The most budget option is spark plugs A27ДМРВ produced by JSC Robert Bosch Saratov.

• German candles from the company BERU–14R-7DU ;
• Japanese NGK–BPR6ES (very frequent replacement, good spark plugs according to reviews);

Candles NGK–BPR6ES in branded packaging in bright colors.

• Another Japanese company is DENSO W20EPR ;
• CHAMPION (England) – RN9YC ;
• From the Czech company BRISK you should take a closer look at the article number LR15YC ;
• BOSCH (Germany) – WR7DC .

Iridium spark plugs

• NGK – BPR6EIX11 ;
• DENSO – IW20TT .

Recommendations from the experts

1. Even if there are indirect signs of faulty spark plugs, it is worth taking the car to a dealership or checking the spark plugs yourself, if possible. If it turns out that only one spark plug is faulty, the entire set will have to be replaced.
2. If you still decide to find the reason yourself, then adhere to some rules: - all manipulations can be carried out only on a cooled engine, otherwise you can break off part of the spark plug so that it remains inside the engine; - work only with a special spark plug wrench, which has a special working area; - dismantle spark plugs only in a room free from wind, snow and other weather conditions to avoid debris getting into the cylinders; - use a compressor.
3. Read the instruction manual carefully, it clearly states what kind, how many and for how long spark plugs are needed.

Spark plugs for Kalina, Priora and Grant - which ones to choose?

Lada Kalina (1st and 2nd generations), Granta and Priora were equipped with both 8 and 16 valve engines. And although they differed for each car, they were still structurally very similar. Therefore, the same spark plugs were installed on all three cars; the differences are only in the article numbers. Spark plugs, as mentioned above, differ on all cars only depending on the number of valves in the engine.

In the original, all three cars are equipped with ordinary nickel spark plugs, with one ground electrode. The main differences between the spark plug for 8- and 16-valve engines are the size of the key for screwing it in.

More details about sizes and original articles in the table below.

*According to Champion nomenclature (Russian standard)

Despite the fact that each car has a different article number of original spark plugs, they are interchangeable. Original spark plugs can be found on sale directly from the manufacturer “ZAZS”. For 8-valve engines they have article number A17DVRM, and for 16-valve engines - AU17DVRM.

The most well-known replacement models from other manufacturers are presented below.

As surveys on some popular automobile communities on the RuNet show, the most popular brands among owners of VAZs of the tenth family are NGK and Denso. In addition to ordinary nickel spark plugs, owners of the cars described in the article often resort to installing more advanced iridium spark plugs. Their service life is consistently three times longer than usual, or even more. In addition, they also slightly improve the responsiveness of the engine. The most popular spark plugs for these cars are from Denso. For 16th grade. this is IK20 at a price of 520 rubles/piece, and for 8 cells. — IW20, price — 590 rub./piece.

Types of soot

The color of the electrode can tell a lot; sometimes in this way you can identify the cause of a breakdown in your car.

• Black carbon deposits suggest a faulty filter or electronic control unit. Black carbon deposits appear when insufficient air mixture enters the cylinder.
• A grayish coating with white tints is a sign of insufficient gasoline in the fuel mixture.
• A thick blackish coating with a characteristic oily sheen indicates systematic filling of candles with oil.
• Red coating - most likely, you are using low-quality counterfeit gasoline instead of gasoline.
