Ignition Coil and Iridium Spark Plugs for BMW Z8 (2000-2002) 4.9L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2000-2002 BMW Z8

What it Does: The complete ignition kit replaces worn factory coil-on-plug packs and degraded plugs on the 2000-2002 BMW Z8 to eliminate high-RPM misfires, stabilize idle, and restore crisp throttle response.

The Stock BMW Z8 High-Heat Ignition Breakdown

The high-revving 4.9-liter S62 V8 engine under the hood of the E52 chassis subjects ignition components to intense thermal stress. Encased beneath decorative engine covers in a tightly packaged engine bay, OEM pencil coils suffer from continuous thermal cycling. Over time, internal epoxy insulation breaks down and primary windings degrade, precipitating dielectric puncture, voltage leakage, and spark blowout near the 7,000 RPM redline. Simultaneously, factory spark plug electrodes experience gap erosion and carbon accumulation, increasing resistance and overworking aging coils until hesitation and check engine lights occur.

The Engineering Solution

This comprehensive service kit pairs eight direct-fit coil-on-plug units with eight high-durability iridium spark plugs. The replacement pencil coils are engineered with high-dielectric epoxy potting, reinforced thermoplastic housings, and premium copper windings to resist heat-induced resistance spikes. Silicone boot seals prevent moisture ingress and dielectric flashover inside the deep spark plug wells. Complementing the coils, the fine-wire iridium center electrode plugs significantly reduce voltage demand, optimize flame kernel propagation, and provide exceptional erosion resistance against rich air-fuel mixtures.
