Ignition Coil and Iridium Spark Plugs for Porsche Cayenne (2017-2018) 3.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2017-2018 Porsche Cayenne

What it Does: Restores factory ignition energy, stabilizes secondary voltage output, and eliminates high-rpm cylinder misfires on the forced-induction 3.0L V6 platform.

The Stock Cayenne Ignition Degradation

The forced-induction EA837 3.0L engine produces extreme combustion chamber pressures and high thermal loads within the tight cylinder valley of the 958.2 chassis. Over time, OEM ignition coils suffer from dielectric breakdown, internal epoxy thermal fatigue, and micro-cracking in the primary copper windings. Coupled with electrode gap erosion on aged spark plugs, this causes increased coil resistance, erratic spark discharge, rough idle, unmetered misfires under boost, and intermittent P0300-P0306 diagnostic trouble codes.

The Engineering Solution

This complete 6-cylinder refresh kit pairs six heavy-duty ignition coils with six fine-wire iridium spark plugs for precise combustion synchronization. The direct-fit coil-on-plug assemblies feature high-grade internal copper windings and reinforced dielectric resin to withstand sustained thermal cycling. The iridium plugs feature laser-welded fine-wire center electrodes and anti-corrosion nickel-plated shells, lowering the required arc voltage, resisting fouling, and maintaining consistent gap geometry under sustained load.
