Ignition Coil and Iridium Spark Plugs for Jaguar X-Type (2002-2008) 3.0L

High-Dielectric Ignition Coil and Iridium Plug Kit for 2002-2008 Jaguar X-Type

What it Does: Direct-replacement complete ignition tune-up kit engineered to restore factory spark energy, eliminate misfires, and stabilize high-RPM combustion across all 6 cylinders.

The Stock X-Type Ignition Breakdown

The AJ30 V6 engine bay subjects the rear cylinder bank coils to extreme thermal cycling beneath the upper intake manifold. Over time, OEM coil housings suffer micro-fractures in the epoxy resin, leading to dielectric breakdown, secondary voltage leakage, and unburned hydrocarbon misfires under load. Furthermore, factory-fitted standard plugs erode at the ground electrode gap, raising the required ignition voltage beyond what degraded stock coils can deliver, triggering stubborn P0300-P0306 diagnostic trouble codes.

The Engineering Solution

This kit combines 6 heavy-duty coil-on-plug assemblies with 6 fine-wire iridium spark plugs for maximum ignition efficiency. The coils feature high-purity copper windings with reinforced thermoplastic housings to resist thermal fatigue and prevent voltage arcing. Matched with iridium plugs featuring laser-welded fine-wire center electrodes, this setup lowers voltage demand, resists spark erosion up to 100,000 miles, and provides stable flame-front propagation for smoother idle and responsive throttle delivery.
