What this part does
The Ignition Coil transforms the low voltage from the vehicle battery into the thousands of volts needed to create an electric spark in the spark plugs, which ignites the air-fuel mixture. In this generation of BMW engines, each cylinder utilizes its own individual coil that sits directly on top of the spark plug in the cylinder head. When a coil fails, it typically causes localized engine misfires, rough idling, hesitation under heavy acceleration, and will trigger a check engine light with a specific cylinder misfire diagnostic code.

Before you order
Verify your exact part number before ordering, as BMW utilized different coil suppliers (such as Delphi and Eldor) which feature slight variations in the connector keyway depending on the production month. It is standard practice to replace the spark plug on the affected cylinder when installing a replacement Ignition Coil to prevent premature failure. While these can be replaced individually, if one assembly has failed due to thermal cycling and age, the remaining coils on the bank may be nearing the end of their service life.
