Ignition Coil and Iridium Spark Plugs for Jeep Commander (2006-2008) 4.7L

Direct-Replacement Ignition Coil & Iridium Spark Plug Kit for 2006-2008 Jeep Commander

Complete Ignition Refresh: Restores factory combustion efficiency, throttle response, and engine smoothness by replacing worn secondary ignition components on the 4.7L V8 platform.

The Stock Commander Thermal Fatigue & Coil Breakdown

The 4.7L PowerTech V8 engine bay in the XK Commander subjects factory coil-on-plug (COP) assemblies to intense heat soak and continuous thermal cycling. Over time, original epoxy potting degrades, leading to internal micro-arcing, dielectric insulation breakdown, and erratic secondary voltage output. Paired with aged spark plugs suffering from widened electrode gaps, this breakdown manifests as intermittent hesitation, rough idle, reduced towing torque, and persistent P0300-P0308 misfire codes.

The Engineering Solution

This comprehensive kit includes 8 direct-fit ignition coils and 8 matching iridium spark plugs engineered to withstand severe underhood environments. The coil packs feature high-grade internal electrolytic copper windings for maximum magnetic saturation and rapid primary-to-secondary voltage transformation. Encased in high-dielectric thermoplastic housings with corrosion-resistant blade terminals, these coils resist voltage leakage. The fine-wire iridium spark plugs offer superior thermal resilience and minimal spark degradation, ensuring consistent flame kernel propagation and reliable combustion under heavy payload demands.
