Ignition Coil, OEM - E60 M5, E63 M6

Ignition coils play a vital role in the performance, efficiency, and health of your BMW S85 V10 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.
