Heat soak from the forced induction setup causes the epoxy potting within the OEM ignition coils to micro-crack, leading to voltage leaks and weak sparks. Simultaneously, factory spark plugs suffer from gap widening and electrode erosion under high-load conditions. This degradation manifests as a rough idle, noticeable power loss during acceleration, blinking check engine lights (CEL), and specific cylinder misfire codes (P0300 series). Ignoring these early warning signs can eventually lead to unburned fuel damaging the catalytic converters, resulting in costly secondary repairs.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive ignition overhaul kit is engineered to exceed factory standards and withstand the high thermal loads of the supercharged V6. The ignition coils feature upgraded copper windings and high-dielectric epoxy housing, preventing voltage breakdown and ensuring a consistent, high-energy spark delivery up to the redline. Paired with premium iridium spark plugs, this kit provides exceptional wear resistance. Iridium's ultra-high melting point prevents electrode degradation, maintaining an exact gap over thousands of miles for complete fuel atomization. The blade-style female and male terminal connectors are precision-machined to ensure a secure, corrosion-resistant mating surface, guaranteeing a perfect plug-and-play installation without the need for splicing or modification.\u003c\/p\u003e\n  \n  \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2014-2019 Jaguar XJ\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eAJ126 3.0L Supercharged V6 \/ X351\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e340 hp \/ 332 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eIC78059159067810910106 \/ UF730\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2014-2019 Jaguar XJ 3.0L V6 Supercharged\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Jaguar Precision Standard\u003c\/h3\u003e\n  \u003cp\u003eDesigned for strict European vehicle tolerances, this ignition service kit guarantees a CEL-free operation and smooth, linear power delivery.
