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. Sometimes 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.

This is the OEM Bosch ignition coil used in M52, S52, M52TU, M54, M56, M62, M62TU, S62, and M73 engines (but may be split into specific model years, see below). BMW has made numerous changes to ignition coil part numbers in recent years but has approved this part number to work in the vehicles listed below. This part number 12131748018 replaces previous BMW part number 12139067830 and 12137599219.

Sold per coil. Connecting boot sold separately.

E46 ignition coil boot

We recommend replacing the rubber boot that connects the ignition coil to the spark plug. Sometimes a bad coil may just be a broken or damaged connector boot. This is especially true on cars with a leaking valve cover gasket where the oil has contamintated the rubber boot and the electrical parts inside. This boot can be replaced on its own without having to buy a whole new coil. This part is also useful if you purchased a coil that did not come with a new boot.

1996-1998 E36 BMW 323is 323ic 328i 328is 328ic M3
