Ignition Coil Pack, OEM Bosch - E36, E34, E32, E31 (12139066468)

Ignition coils play a vital role in the performance, efficiency, and health of your M42, M50, S50, and M60 BMW engine. Each cylinder gets its own ignition coil for optimum efficiency (no more spark plug wires) and it fires at precisely the right time to ensure a complete burn of the fuel/air mixture. A bad coil will result in misfires, rough running, stumbling, poor fuel economy, and other engine issues. Also, unburnt fuel will also damage catalytic converters and O2 sensors. Diagnosis of misfires and rough running almost always starts with the ignition coils. You can usually isolate faulty coils by moving them to different cylinder banks. However, we always recommend replacing coils in complete sets to eliminate the damage to computers, control modules, and other electrical systems from a voltage spike.

Price listed is per coil. This part number includes the rubber connector boot. For M42 engine, remove the rubber boot.
