Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2002-2008 Jaguar S-Type
What it Does: Restores factory secondary ignition voltage and combustion efficiency across all six cylinders by replacing aged coil packs and worn spark plugs with matched, high-dielectric components.
The Stock S-Type Thermal Degradation and Misfire Vulnerability
The AJ-V6 engine configuration locates coil-on-plug packs deep within the cylinder head spark plug wells, subjecting factory epoxy insulation and internal copper windings to extreme thermal cycling and dielectric breakdown. Over time, heat-induced micro-fracturing in the OEM coil casings causes high-voltage arc-over, leading to intermittent misfires (P0300-P0306), rough cold starts, unburnt fuel fouling catalytic converters, and sluggish throttle response under load.
The Engineering Solution
This 6-cylinder ignition kit incorporates reinforced, high-dielectric PBT plastic housings engineered to resist thermal degradation and internal breakdown. High-purity electrolytic copper primary and secondary windings maximize voltage step-up efficiency for a hotter, more stable spark discharge. Paired with fine-wire iridium electrode spark plugs featuring high-alumina ceramic insulators, this setup requires lower firing voltages, resists carbon fouling, and guarantees clean combustion across the powerband.
