AC DELCO D555 [IGNITION COIL] - QTY 4

This AC DELCO ignition coil (Set of 4) are new parts. They are the same pieces that you would receive if you purchased them from your local GM dealer.

The ignition coil is a crucial part of your ignition system. It's function is to convert the 12 volt power of your vehicle's electrical system in to 35,000 or more volts. This produces a high intensity spark at the spark plug which then ignites the fuel in the cylinder. Coils in general will wear out over time. This will cause a misfire condition where the car looses power especially at higher engine RPM.
