Ignition for BMW E90 M3 S65 4.0L

Clear BMW chassis

Your BMW's ignition system is critical for smooth engine operation. This category contains parts used in the BMW ignition system, including spark plugs, ignition coils, spark plug wires and boots, ignition rotors and caps, distributors and distributor caps. On most 1991 and later model BMWs, your car has what's known as a coil-on-plug system, where each cylinder has its own ignition coil that sits directly atop the spark plug (so you won't have spark plug wires on those BMWs.) A fresh set of spark plugs is an essential part of any BMW engine tune up.

The Turner Motorsport S65 Ignition Service Kit restores ignition timing and ionic knock-sensing accuracy on the BMW E9X M3 S65 engine. Worn spark plugs alter cylinder electrical resistance, disrupting ionic current knock detection across the ignition coils. Replacing all eight NGK plugs, S65 coils, and applying AGS dielectric boot protector restores precise combustion and knock monitoring.
