What Does an Ignition Coil Do?

The Ignition Coil (also known as a Coil Pack) transforms the battery's low voltage into the high voltage (thousands of volts) needed to create a spark at the spark plug. This spark ignites the air-fuel mixture in the combustion chamber, powering your engine. Modern engines typically use individual coils for each cylinder (coil-on-plug design) to ensure precise ignition timing and optimal performance. Without properly functioning ignition coils, your engine will misfire, run poorly, or may not start at all.
