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.
Replacing spark plugs
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.

I’ll describe the whole procedure a little, maybe this information will be useful for girls or beginners.
The procedure for replacing spark plugs on a Lada Kalina:
Before this procedure, it is advisable to wipe everything well and clean it from possible oil stains or dust so that no debris gets inside the cylinder. Now we need either a spark plug wrench or a 21mm long socket.
We remove the wires one by one, you will have to make a little effort, since they fit quite tightly.
Personally, my electrode condition was normal, there were no deposits, oil film or soot on them, the only thing was that there was a reddish coating. And this is also not very good and indicates that the fuel with which I fueled my Kalina contained iron-containing additives, the so-called ferrocenes. This can lead to misfire, loss of power and increased fuel consumption.
When we screw in new spark plugs, it is best to first tighten them by hand, and only then use a wrench. Although, it is quite difficult to mix up the wires! But I remember an incident with my father’s VAZ 2112 16-valve, when we put the wires on incorrectly and started the car - it worked like a tractor, all the cylinders were out of tune. After you have installed a new spark plug, put on the wire and carry out exactly the same operation with the remaining cylinders!
That's all! Tighten it better so that no air is allowed to pass through, otherwise over time the spark plug may tear out along with the thread, then you will have to spend another certain amount of money on repairs, but do you need it? At the end of my topic, I would like to arrange a short survey about who uses which companies, besides NGK, and what are their impressions? Let's discuss in the comments below!

HOW TO REPLACE CANDLES FOR VAZ 2170, 2171, 2172 LADA PRIORA WITH YOUR OWN HANDS.
If you have everything, then you can proceed:
1. First, remove the decorative plastic casing.
2. Next, disconnect the ignition coil terminal.
3. Unscrew the coil mounting bolt.
4. Using a flathead screwdriver, remove the ignition coil.
5. The spark plug is located in a recess, in the so-called spark plug well, so to unscrew it you will need an extension cord.
6. Be careful, if you notice traces of oil in the spark plug well, be sure to find out its origin; the engine may need immediate replacement of the cylinder head gasket.
7. If this is your first time replacing spark plugs, then it will take some effort to unscrew the spark plugs; in some cases it is simply impossible to do this with a simple spark plug wrench. To do this, you will have to buy a special spark plug socket with a knob.
8. So, unscrew the spark plug, be careful not to accidentally break the spark plug insulator, since it will be quite difficult to remove the fragments, and if, God forbid, they get into the cylinder, then you will need to completely disassemble the cylinder head.
9. Remove the spark plug from the well; if this does not work, use the removed ignition coil, put it on the spark plug shank and try again.
10. The candle has been removed, now you can look at its condition.
11. Draw a conclusion based on the table above. If the spark plug insulator is clean and does not fall into any of the categories, everything is fine with your engine.
12. Install the new spark plug into the head, then reinstall.
13. Attention! Tighten the spark plug without using a wrench; the spark plug should twist easily without any effort. If you break the threads in the cylinder head, you will need repairs, which are not cheap, plus you will create a lot of trouble for yourself.
14. Do everything carefully and take your time. When the candle is screwed in, use the wrench and tighten the spark plugs. Again, remember that everything should be in moderation; if you overdo it, you can break the thread.
15. Now all that remains is to put the ignition coil in place, tighten the mounting bolt and put the connector in place.
Repeat the procedure for all other spark plugs.
That's all, now you know that replacing spark plugs on a Lada Priora is a procedure that you can do yourself!

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 25–30 N. m.
Attention! Over-tightening the spark plugs can damage the threads in the spark plug holes in the cylinder head.
We replace the remaining spark plugs in the same way.
On an 8-valve engine
We change the spark plugs ourselves
Let's say all the wells were open, and now you can see the contacts of the spark plugs.
Only one well is open here
Taking a high 16 socket wrench, dismantle each spark plug. It is better to use a special tool - that is, a “spark wrench”.
All spark plugs should come out easily
Installation is carried out in the reverse order, but the following requirements are observed:
- First, taking the spark plug body with your hands, screw it in without using a key;
- The key must be rotated with a force of 25–30 N*m. Do not exceed these numbers!
It is usually recommended to change spark plugs “one at a time”. This advice will be useful for beginners.
If there is oil inside the wells, you need to “get it wet”. The oil itself will not cause harm, but sand and dust will get into the cylinders with it.

How do spark plugs work?
Spark plugs are a device for igniting the fuel-air mixture in an engine. They consist of a metal body, an insulator and a central conductor. They are located in the spark plug wells, which, in turn, are located in the engine cylinder heads. High-voltage wires are attached to the top, supplying voltage to the spark gap.
Experienced motorists advise changing them every 20 - 30 thousand kilometers. Or earlier if the condition of these parts requires it. Thus, the need to replace spark plugs on Kalina may be indicated by problems with the starter, a decrease in engine power, car twitching and vibration when driving.
The process of replacing spark plugs
Before the replacement procedure, it is advisable to blow out or wipe the casing and cylinder head. This is done to prevent dust, dirt and debris from entering the engine block, which can lead to catastrophic consequences.
For work we will need: a 10 mm socket, a spark plug wrench or a 16 socket with an extension (For eight-valve engines you will need a 21 socket with an extension).
Step-by-step instructions for replacing spark plugs on a Kalina with a 16-valve engine
- With a sharp jerk upward, remove the plastic engine casing.
- We disconnect the wires from the ignition coils, then use a 10 mm wrench to unscrew the mounting bolts and remove the coils from the spark plug well.
- We unscrew the spark plug with a 16mm wrench and insert a new one.
Step-by-step instructions for replacing spark plugs on a Kalina with an 8-valve engine
- Remove the wire end (don't be afraid to use a little force).
- We unscrew the spark plug with a 21 key and replace it with a new one.
When installing candles, you should not use excessive force, otherwise you can break the thread of the well, which can lead to costly repairs. In Kalina, replacement of spark plugs for 1.4 liter and 1.6 liter engines is similar.
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.
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.

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.
Do you use a torque wrench when replacing spark plugs?

If the engine in your car runs unevenly, stalls, stalls, or has low idle speeds, then the cause may be the spark plugs. The article “How to determine the condition of spark plugs on a Kalina” will help you determine this more accurately. As a rule, spark plugs are changed every 40 thousand km. But replacing spark plugs may be required more often, depending on the quality of the spark plugs themselves, the quality of the fuel used and engine wear. When using gas as fuel, it is recommended to change spark plugs every 10 thousand km. In this article you can learn more about how to replace spark plugs.
Attention! Spark plugs are changed all together. Even if only one of them is faulty, the other three that are working should also be replaced.
- We take a ratchet wrench with a special head for spark plugs No. 21. Unscrew the spark plug by turning the key counterclockwise.
- We take a new candle and compare it with the old one. They must be the same. Insert into the mounting hole. And turn it by hand a couple of turns clockwise. This must be done by hand so that the candle is guaranteed to be wrapped along the thread.
- We finally clamp the spark plug with a key with a little force. We put on a high-voltage wire. Ready.
We change the other three candles in the same way.
Now we start the engine and check if it works normally. Fine. Close the hood and you're good to go.

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.
9. Put on the motor cover.
There are four grooves on the cover, and four matching holes on the motor. Just put the grooves into the holes and press.
How to replace spark plugs in Lada Kalina
Replacing spark plugs is an important procedure that is performed every 30 thousand km or in case of their malfunction. The reason why spark plugs are replaced unscheduled may be unstable engine operation, excessive fuel consumption or poor engine starting. In addition, poor throttle response or when the engine stalls can be evidence of faulty spark plugs. You can even determine the condition of the spark plugs by external signs; below I will give a table by which you can decide whether you need to replace the spark plugs or not.
Today I will talk about how to replace spark plugs on a VAZ 2170, 2171, 2172 (Lada Priora 16 valve)
Before you start replacing, take care of new spark plugs, choose one you like from the options in the auto store.
Replacing spark plugs on a Lada Priora is impossible without a special 16″ socket wrench with an extension. There must be a magnet in the spark plug wrench or head so that the spark plugs can be held suspended.
Selection of components
Symptoms of incorrectly selected spark plugs:
From the factory, “AU17DVRM” spark plugs will be installed on any VAZ 16-valve engine. They are produced in Saratov under license from BOSCH. There are also two complete analogues recommended by VAZ: DR15YC-1 (BRISK), as well as FR7DCU (BOSCH).
Products
In winter, you can switch to a lower heat rating - “AU14DVRM” candles are suitable. All analogues are presented in the table.
Hi all. Today we will replace spark plugs on a second generation Lada Kalina with a sixteen valve engine.
I recommend buying Denso candles. Inexpensive and go from replacement to replacement without problems. Order number: Q20PR-U11 .
To replace spark plugs you will need:
- open-end wrench for ten
- seven-head wrench
- a long spark plug wrench because the wells are deep
