Decades of severe thermal cycling degrade the original epoxy potting and internal secondary copper windings. This insulation breakdown induces internal high-voltage arcing, fluctuating coil primary resistance, and secondary boot dielectric puncture. The resulting weak spark or intermittent ignition discharge triggers hesitations, unstable idle, catalytic converter fouling, and diagnostic trouble codes (DTC P0300 through P0306).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit features six heavy-duty ignition coils paired with fine-wire iridium spark plugs designed specifically to combat heat soak in the \u003cstrong\u003eAJ16\u003c\/strong\u003e engine bay. Each coil utilizes high-grade magnetic silicon steel cores and temperature-resistant potting compound that resists thermal breakdown up to 300°F. Reinforced silicone boots with internal corrosion-resistant springs block moisture intrusion and stop high-voltage flashover. The matched iridium center-electrode spark plugs significantly reduce ignition voltage demand, sharpen flame kernel propagation, and provide stable electrode gap retention over extended service intervals.\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; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1995-1997 Jaguar XJ6\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eAJ16 4.0L I6\u003c\/strong\u003e \/ \u003cstrong\u003eX300\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e245 hp \/ 289 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e68080580AB\u003c\/strong\u003e, \u003cstrong\u003eUF384\u003c\/strong\u003e, \u003cstrong\u003e68242286AA\u003c\/strong\u003e, \u003cstrong\u003e68242286AB\u003c\/strong\u003e, \u003cstrong\u003eUF754\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1995 Jaguar XJ6 Base \/ Sovereign \/ Vanden Plas 4.0L L6 (AJ16)\u003c\/li\u003e\n  \u003cli\u003e1996 Jaguar XJ6 Base \/ Sovereign \/ Vanden Plas 4.0L L6 (AJ16)\u003c\/li\u003e\n  \u003cli\u003e1997 Jaguar XJ6 Base \/ Sovereign \/ Vanden Plas 4.0L L6 (AJ16)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the X300 XJ6?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1995-1997 Jaguar XJ6 equipped with the \u003cstrong\u003eAJ16\u003c\/strong\u003e 4.0-liter engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the iridium spark plugs pre-gapped for the AJ16 engine?\u003c\/strong\u003e\u003cbr\u003e Yes, the spark plugs come pre-gapped to factory specifications, though checking gap tolerance prior to installation is always recommended.\u003c\/p\u003e\n\n\u003ch3\u003eThe Jaguar Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet stringent European saloon tolerances, this ignition service package preserves the smooth harmonic delivery and refined throttle response expected of classic British engineering without triggering check engine lights or intermittent misfire faults.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50593977336056,"sku":"DS-EOFYEEZ1P","price":104.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-and-iridium-spark-plugs-for-jaguar-xj6-1995-1997-4-0l-1.jpg?v=1790054917","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-jaguar-xj6-1995-1997-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
