Ignition for BMW 3 Series E46 (1999-2005)

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.

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code, but not always a check engine light. A misfire code may be related to an ignition coil, but could be from other things as well. ometimes, a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.
