Advice 1: How to choose spark plugs

To date, universal spark ignition, suitable for any car on the market does not exist. However to choose the right candle quite simply, if you approach the issue wisely.
A properly fitted spark plugs - the key to excellent performance of the engine
You will need
  • - the instruction manual for your car or vehicle passport (PTS)
  • - protective gloves
  • - candle key
Instruction
1
Determine the type of its engine.
Just look at your title or the manual of your car, if you cannot answer this question. If you have a diesel, then you need candle bulbs glow or spark ignition. For the petrol engine, you need spark the spark plugs.
2
Unscrew one of your old candles. If access to the spark plugs is not limited, it is quite easy to do with a special candle key. Lift the hood of your car, locate the candles, remove one wire to the pin and carefully remove it.
3
Go to the store. There you can either pick up the candle according to your make and model of the car or show the old candle, with which consultants and will select a new set.
For passenger cars usually fit the spark plugs with thread type "A". Length of candle, the size of her head and the heat rating is determined by the vehicle manufacturer, and the number of electrodes and the material from which they are made, you can choose from.
4
Select the material of the electrodes.
A standard candle is supplied with one copper electrode. In addition to copper, the electrodes of the spark plugs is made with addition of iridium, yttrium and platinum. Are candles with such electrodes is several times more expensive than their copper companions, but refractory metals give a much greater resource, that is, the candles last longer and burn slower. You also get more stable and powerful electrical charge, which is important for engine operation: the course will be smooth,with no failures in the ignition.
If funds allow, you make a choice in favor of platinum spark: fuel consumption with exhaust emissions will be reduced by a few percent, and replacement candles will not need for many years. If no extra money - the copper candle is also nice, although there are several less reliable and durable.
5
Determine the desired number of electrodes.
Standard candles are produced with one side electrode, is improved with several. Manufacturers claim that multi-electrode spark plugs contribute to the operation of the engine without failure and make the system of ignition more reliable. The advice here can only be the same as when choosing the material of the electrodes: use common sense.
Note
For each car manufacturer installs the necessary distance between the Central and side electrode. Try to handle the candles with care and do not drop them, not to displace the electrodes.
Useful advice
Change all the candles at the same time: so there will be less chance that the engine will start to troit.

Advice 2 : How to choose spark plugs for Lada

To promote the good work of your car, will certainly choose the most suitable spark plug for it. The automobiles are machines that require installation of candles such well-established brands such as BRISK, BOSCH, NGK, CHAMPION.

How to choose spark plugs for Lada
You will need
  • - candle key;
  • - stand for testing the candle.
Instruction
1
Choose candles based on parameters such as surface number and size. Heat rating determines the operating temperature. The higher the mode, the colder the candle, and, consequently, it is possible to operate at the lowest temperatures. Must be correctly matched to the size of the candle could stand in its place without effort. For automobiles, a good production of firm BOSCH, with the Central electrode. Copper core which is protected by a layer of chromium and Nickel.
2
Choose a cheap spark plug, suitable for automobiles. They are produced by the company BRISK. This is a classic production, which electrode consists of a Nickel alloy. Note the high coefficient of thermal conductivity of these candles. High reliability different candles Japanese company NGK and CHAMPION of the American firm. They are well proven, as they are durable due to iridiu in the Central electrode.
3
Do not purchase spark plugs that have visible damage or cracks. Be sure to check before installation if the gap between the electrodes in size. The electrodes may receive the carbon, which you should remove to prevent the car down.
4
To check purchased the spark plugs, put them in the chamber and set the pressure about 10 kg/cm2, and then connect the current 22 kV. If you follow these steps, you should see the spark. If it is continuous, set a candle in the car. If it occurs intermittently, so your candle is defective.
5
Find out the value of the spark gap for your model VAZ. Also do not supply voltage on the plugs more than 18 kV when tested.
Note
It is possible to consider the high price of spark plugs to be justified, if they have the iridium and platinum tips.
