Ignition Coil and Iridium Spark Plugs for Jaguar S-Type (2000-2001) 3.0L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2000-2001 Jaguar S-Type

Direct-fit primary ignition overhaul: Replaces degraded factory coil-on-plug units and worn spark plugs to eliminate cylinder misfires, rough idle, and spark blowout under load.

The Stock S-Type Ignition Breakdown

The AJ-V6 engine bay in the X200 chassis produces substantial thermal load within the cylinder head valleys. Over time, heat soak degrades the factory coil packs' internal epoxy potting and compromises the secondary winding insulation. This thermal degradation leads to dielectric breakdown, high-voltage leakage, and unburned fuel entering the exhaust stream, triggering catalytic converter damage and persistent misfire codes.

The Engineering Solution

This 6-cylinder ignition kit addresses electrical breakdown using reinforced internal copper windings and high-grade silicone dielectric boots that resist cracking and thermal fatigue. Matched with fine-wire iridium spark plugs, the assembly ensures low firing voltage demand, consistent spark kernel formation, and stabilized gap geometry across high-mileage heat cycles.

The Jaguar Precision Standard

European engine management demands exact primary and secondary resistance parameters. This kit meets original factory impedance thresholds to guarantee zero misfire-induced CELs, restore factory throttle response, and ensure smooth, balanced combustion across the entire rev range.
