Ignition Coil and Iridium Spark Plugs for BMW Z4 (2006-2008) 3.2L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2006-2008 BMW Z4 M

Direct-fit ignition overhaul kit engineered to eliminate secondary ignition breakdown and restore precise combustion timing across all six cylinders.

The Stock S54 High-RPM Ignition Degradation

The high-revving 3.2L S54 engine generates extreme thermal loads under the valve cover, subjecting factory coil-on-plug boots and internal epoxy potting to rapid heat degradation. Over time, thermal cycling causes micro-arcing through cracked dielectric insulation, while copper core plugs experience rapid electrode erosion. This breakdown manifests as high-RPM misfires, erratic idle stability, delayed throttle response, and secondary ignition fault codes.

The Precision Ignition Engineering Solution

This comprehensive ignition service kit features six upgraded coil packs built with premium internal copper windings and high-dielectric epoxy potting to withstand high cylinder pressures up to the 8,000 RPM redline. Paired with fine-wire iridium spark plugs, the kit reduces required firing voltage, prevents spark blowout, and provides superior resistance to thermal fouling. Direct-fit blade terminals and factory-keyed connectors ensure plug-and-play installation without wire harness modifications.
