S65 Ignition Service Kit (E9x M3) (08-13)

Spark plugs and ignition coils are a pretty common overlooked item. This occurs because the components are out of sight, 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.
