This spark is essential to start your engine and keep it running smoothly.

The Role of a Spark Plug

The primary role of a spark plug is to ignite the fuel and air mixture in your engine's combustion chamber. It creates an electrical spark that ignites the fuel and air mixture, which creates a small explosion. This explosion pushes the piston down, which generates power that drives your engine.
