Candles are an important element of any engine. These elements participate in the process of ignition of the fuel mixture. The candle has a fairly solid construction. But the item works under high loads and exposed to wear and tear. Except for normal wear and tear on this element affects and poor quality fuel. Candles need to be replaced periodically. Let's look at what should be the frequency of replacement of spark plugs, how to determine that it is time to change a detail, and also learn about what should be the gap.
If the car is out of warranty, here in any case all maintenance activities are carried out strictly according to the regulations of the manufacturer. Different brands reglementary the replacement of candles in different runs. This is often a period of 40-80 thousand kilometers. These figures have a huge run-up. The fact that different vehicles are equipped with different candles. The replacement Interval depends on the materials and technologies used in the production process of the item. Also, the replacement interval of the spark plugs depends on their resistance to high temperatures (heat rating) and voltage.
Modern candles can be divided into Nickel and platinum. First change every 30-45 thousand kilometres. The second go around 70-80. Resource candles with iridium coating depends on the thickness of the Central electrode. The figure may vary in the range from 60 to 120 thousand kilometers.
Ideally, if the replacement will be performed with each oil change in the engine. The average is 15-20 thousand km. But someone changes the oil more often, e.g., every 8 thousand, which is very important for cars that are in operation in our country. In addition, if for the engine it is necessary to put brand of the candle, it will cost such a replacement is not cheap. Yes, and so frequent replacement frequency of spark plugs will not save you. How many candle can really work?
And here is where the experts recommend not to pull once again with replacement parts, no matter how quality they may be. Even the candle with iridium or platinum coating in our country must change for the new no less than 40-50 thousand kilometers. If the motor is cheap brand of spark plugs from “Auchan”, these elements should be changed not less than once in 10 thousand kilometers. Cheap candle has a much smaller resource, in contrast to dear. But do not forget about fakes.

If the owner of the car broke the replacement frequency of spark plugs and installed new parts, then immediately this will not lead to any serious consequences. If this is an expensive candle, it could and does not work on your resource. But one with such candles the car just won't start. There are several signs that notify the owner that will have time soon to change spark plugs. We'll cover that next.
The failure of spark plugs the engine will start to troit. It will twitch when driving and at idle. Also having problems with starting the power unit. The starter will spin the flywheel, but the engine will not start. The spark may disappear if the gap on the plugs is too big. Will increase the fuel consumption and the amount of carbon dioxide in the exhaust gases. Also faulty spark diagnosed by the deteriorating dynamics. The engine will not gain momentum, as before. Also will drop its power.
If you ignore all these symptoms, then after some time the motor may become damaged. Do not neglect regular replacement. It's cheaper than an overhaul.
One of the most sad consequences – detonation in the cylinder. This produces a blast, which, depending on the quantity of the fuel mixture can be forced to detonate the entire charge in the combustion chamber. During heavy engine vibration will experience mechanical and thermal loads close to maximum. In the result, burn pistons, cylinder head gaskets, the spark. The shock wave disrupts the oil film in the upper parts of the cylinder. This leads to increased wear of crank.
When checking the parts visually, many novice car owners of scary black soot on the spark plugs. The reasons of this phenomenon may be different. The type of soot will tell you about the motor. Fat Black oily soot, which is formed on the electrode and on the thread, indicates a large amount of oil which enters the cylinders. It gets there because of worn oil scraper caps, piston rings or valve guide bushings. Candles in this case are not the cause of the problem.
Consider a dry black soot on the spark plugs, the reasons for its formation. The first symptom – it is a violation of the candles, which may indicate a weak spark. The second reason – low compression. If you noticed velvety Nagar, you should check the pressure in the cylinders. On old petrol engines, the carbon black may report about incorrect settings of the carb. In inverter engines, this indicates a problem in the fuel pressure regulator. Another reason - too rich mixture. Also black soot on the candle may indicate clogged air filter. The last is changed every 10 thousand kilometers.
You should Also consider the plug gap. Increased parameter increases the likelihood of cliff sparks. The motor will troit. And at high speeds possible misfiring. Small gap on spark plugs – it is also not good. This is one of the reasons why candles are filled with gasoline. As a result, burns out the ignition coil.
You can Check the detail not only on the behavior of the car. There are other ways that can help to make sure it is working. So, you can check the candle on the presence of spark with a multimeter or use a special device to check the spark plugs.
With the help of this device you can check inside details of short circuit. But the thing is that after this diagnosis it is difficult to talk about the health of the candles. To test the wires from the multimeter connected so that one cord was connected to the output, and the second – with cap. After that you should see a spark.
A Device for checking the spark plug – a gun, which you can check the candle on the performance. Often the audits are conducted under pressure. This device can be purchased at any major shop.
To start testing the candle is inserted into the groove and put on special cap. Next, click the trigger of the gun and see whether there is a spark and the lights do light. If so, then the item is working. But again to an absolute guarantee on this unit difficult. If the bench spark is good, not the fact that the same spark is in the engine. In the combustion chamber a different pressure. But if the candle does not work in the device, it is definitely not alive. Change them with better kit.
So we figured out how long to change spark plugs. As you can see, you need to know not only the frequency of replacement, but also the first signs of poor operation of the ignition system.
