(4) L92 Truck Style Ignition Coil For GM GEN 3 & GEN IV

Engine start and idle issues can be a pain; FAST coil packs can help resolve cylinder misfires and rough idle issues. They are designed to work with your vehicle's ignition system to provide a smooth and reliable spark signal. Ignition coils have the engineered advantage of having one less link to replace and troubleshoot when having engine ignition complications. They eliminate the mechanical connection of the distributor, taking the signal directly from the ECU to the spark plug. So, rather than inspecting two wired connections, a distributor, and plugs, you have only one wire, one coil, and one plug per cylinder. Find out which cylinder you need to work on from the ECU, or simply by process of elimination. They are extremely easy to replace, with proper access. FAST coil packs will have you back to all cylinders in no time.
