An ignition coil is a crucial component of an internal combustion engine that converts the vehicle’s battery voltage (typically 12 volts) into the thousands of volts necessary to create an electric spark in the spark plugs. This spark ignites the air-fuel mixture in the engine’s cylinders, initiating the combustion process that powers the vehicle.
Maintaining properly functioning ignition coils is essential for optimal engine performance, fuel efficiency, and reduced emissions. A faulty ignition coil can lead to various issues, including difficulty starting the engine, misfiring, rough idling, and reduced power output.
