How much does it cost to clean the spark plug of a car?

The cleaning of automobile spark plugs is generally around 20 yuan. It is generally recommended to clean the spark plug every 5000 kilometers. Automobile spark plugs have two main functions: 1, generating sparks, igniting mixed steam to generate electricity, sealing the spark plug hole and maintaining the pressure in the cylinder;

2. If the spark plug is not replaced in time, although the spark plug can ignite, the combustion of the spark plug will lead to the decrease of ignition performance, incomplete combustion of oil and gas, increase fuel consumption, increase exhaust emissions, and make it difficult to start and accelerate. Insufficient combustion will also lead to engine flameout, which will cause certain damage to the engine;

3. The ignition system of gasoline engine sends high voltage current into the cylinder to generate electric spark, thus igniting combustible mixture. It mainly consists of a connecting nut, an insulator, a connecting screw, a center electrode, a side electrode and a shell, wherein the side electrode is welded on the shell.
