The ignition coil is a critical component of your vehicle's ignition system. It transforms the low voltage from the battery into the high voltage required to create a spark at the spark plug. This spark ignites the fuel-air mixture in the combustion chamber, powering your engine. A failing ignition coil can lead to a variety of issues, including misfires, rough idling, poor acceleration, and decreased fuel economy.
