Spark plugs are an essential element of the engine system. They play the main role in his work. From time to time, car owners are faced with the problem of breaking through the candles. To solve the problem, you need to check them.
First of all, the high-quality start of the engine depends on the candles. Also, their condition affects the stability of the car at idle. If the spark plug fails, other elements of the ignition system may also fail. It is also worth noting that the catalytic converter of the exhaust gases can break down. It has a high cost. Defective plugs must be "calculated" and replaced as soon as possible. It is recommended to use candles recommended by the manufacturer. If you do not have the opportunity to purchase analogs, then you need to observe two basic rules when choosing. New candles should be close in shape to the standard ones. They should also have similar thermal characteristics. These characteristics are the main ones. The heat number characterizes the degree of thermal conductivity of the spark plug. It is highly not recommended to install candles on the car that have a shortened threaded part. The fact is that they quickly become clogged with carbon deposits and become unusable. Note that during operation, the gap between the electrodes will increase by 0.015 mm for every 1000 km of run. That is why it is best to perform maintenance every 5000 km. Most manufacturers recommend replacing the spark plugs every 30,000 km. When buying, be sure to check them in the store. Some manufacturers provide a warranty for these products. Many Japanese cars are fitted with candles that have original designs. For example, designs are often used that have three side electrodes, or do not have them at all. Keep in mind that a three-electrode plug also has disadvantages. The fact is that only one spark is formed, which can break through the gap that has the least resistance.
