What do spark plugs do?

Spark plugs are responsible for delivering the electric current from the ignition system to the combustion chamber of the engine. This spark ignites the air/fuel mixture, which in turn powers your car. Through this combustion process, the energy needed to start and keep the engine running is created, making spark plugs crucial for engine performance. By maintaining precise design tolerances, spark plugs also help optimize fuel efficiency, allowing your vehicle to achieve better gas mileage. Additionally, well-functioning spark plugs contribute to reduced emissions by ensuring a more complete burn of the fuel mixture.
