Spark plugs are small components that face the combustion chamber of your engine. They conduct electricity and produce a spark that ignites the air-fuel mixture in the engine. There is typically one spark plug on every cylinder of the engine. The spark plugs draw electrical power from the ignition coil.

Spark plug maintenance
Spark plug replacement is a routine maintenance item that should be done at the interval recommended by your manufacturer.
