ACDelco GM Original Equipment Ignition Coil Kits are designed, engineered, and tested to rigorous standards, and are backed by General Motors. An ignition coil is an induction coil in a vehicle's ignition system which transforms the battery's low voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel. ACDelco GM Original Equipment parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some ACDelco GM Original Equipment parts may have formerly appeared as GM Genuine Parts (OE) or ACDelco Professional.
