N54 Ignition Service Kit

Replace each component of your N54 powered BMW ignition system, featuring OE Delphi ignition coils and one step colder NGK ILZKBR7B-8DG spark plugs.

Re-gap NGK plugs to 0.7mm (0.0275″) for OE or 0.56mm (0.022″) for high boost

Spark plugs and ignition coils are a pretty common overlooked item. This occurs because the components are out of site, out of mind so to speak: that is until your engine starts to have misfire codes.

Spark plugs wear out over countless thousands of ignition cycles. The wear results in misfires and poor ignition performance because the gap between the center electrode and ground electrode becomes too big. Once this occurs with a spark plug it will need to be replaced.

Ignition coils provide the energy required for the spark plug to ignite the fuel mixtures. Over countless thousands of ignition cycles the ignition coils will wear out. We typically see ignition coil boots wear out causing poor insulation between the spark plug and coil.

We highly recommend also ordering a 14mm 12 point spark plug socket unless you otherwise own one.
