Ignition Coil and Iridium Spark Plugs for Porsche 911 (2011-2012) 3.6L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2011-2012 Porsche 911

Direct-fit ignition overhaul: Restores factory spark energy, resolves high-RPM misfires, and stabilizes idle across all six cylinders on the 3.6L flat-six platform.

The Stock 911 Thermal Stress and Insulation Breakdown

Due to the low-slung, rear-engine layout of the 997 chassis, ignition coils sit directly adjacent to high-heat exhaust headers. Continuous thermal cycling breaks down factory epoxy potting and rubber boots, causing dielectric micro-fractures and secondary voltage leakage. Over time, this leads to spark blowout under load, sluggish throttle response, erratic idle, and catalyst-damaging cylinder misfires.

The Engineering Solution

This complete 6-cylinder ignition service kit features coil-on-plug assemblies manufactured with high-density internal copper windings and heat-resistant dielectric epoxy to eliminate heat soak failure. Paired with fine-wire iridium spark plugs, the system lowers required firing voltage while maximizing spark intensity, ensuring complete fuel atomization, crisp throttle response, and dependable high-RPM combustion.
