Positioned directly above the cylinder heads, these coils endure extreme heat soak cycles. Over time, internal epoxy and secondary windings break down, causing increased electrical resistance and ignition misfires. This weak combustion translates to rough idling, hesitation under heavy throttle, and premature plug fouling. Furthermore, standard OEM plugs erode naturally over time, increasing the spark gap and forcing aging coils to work harder, which drastically compounds drivability issues under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis OEM-grade ignition coil and Iridium spark plug package provides a comprehensive ignition system refresh. The upgraded coils feature heavy-duty copper wire windings engineered to lower internal resistance and maximize voltage output. This ensures a more consistent spark under high loads and RPMs. The coil housings are constructed from heat-resistant thermoplastics to withstand prolonged engine bay temperatures, preventing the cracking and arcing that plagues aging factory units. Paired with precise Iridium spark plugs featuring a fine-wire center electrode, this kit requires less primary voltage to generate a spark while delivering superior energy transfer. The iridium tips resist arc erosion, ensuring the spark gap remains precisely calibrated over tens of thousands of miles.\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;\"\u003e2010-2012 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;\"\u003eAJ133 5.0L V8 \/ X250\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;\"\u003e385 hp \/ 380 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;\"\u003eUF618, LR010687, AJ811378, 8W93-12A366-DA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2010 Jaguar XF 5.0L V8\u003c\/li\u003e\n  \u003cli\u003e2011 Jaguar XF 5.0L V8\u003c\/li\u003e\n  \u003cli\u003e2012 Jaguar XF 5.0L V8\u003c\/li\u003e\n  \u003cli\u003e2010-2012 Land Rover Range Rover 5.0L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe European Precision Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned for the sophisticated engine management systems of modern European V8s, these coils provide precise voltage control to keep your AJ133 running smoothly, ensuring reliable power delivery without triggering frustrating Check Engine Lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":49748883964152,"sku":"DS-EZBM79MPR","price":149.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-land-rover-range-rover-2010-2012-5-0l-v8-1.jpg?v=1782927050","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-land-rover-range-rover-2010-2012-5-0l-v8","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
