Prolonged heat soak breaks down the internal epoxy potting of the OEM coils, leading to micro-cracks in the housing. This degradation reduces voltage output, causing hesitation under boost, rough idling, and inevitable P0300-series misfire codes. Simultaneously, factory spark plug electrodes erode, widening the gap and further straining the weakening ignition coils under higher cylinder pressures.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ignition coil and iridium spark plug kit is engineered to withstand the extreme under-hood temperatures of the supercharged X250 and X260 chassis. The coils feature upgraded high-temperature epoxy and reinforced blade connectors to ensure stable electrical connections and prevent thermal breakdown. Paired with iridium-tipped spark plugs, which offer superior conductivity and an exceptionally high melting point compared to standard copper or platinum, this combination ensures a precise, concentrated spark. This highly efficient burn maximizes supercharger response, stabilizes idle quality, and restores factory power delivery.\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;\"\u003e2013-2020 Jaguar XF\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 SC V6 \/ X250 \u0026amp; X260\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;\"\u003e340-380 hp \/ 332-339 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 (Interchange: UF727, C2Z18619, LR035548)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2013-2020 Jaguar XF 3.0L Supercharged V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jaguar Standard\u003c\/h3\u003e\n\u003cp\u003ePrecision is paramount in European forced-induction applications.
