Over time, this intense heat soak degrades the internal epoxy and secondary windings of the factory ignition coils, leading to internal arcing, increased resistance, and inevitable misfires under load. Furthermore, standard OEM spark plugs suffer from accelerated electrode wear under supercharged boost. As the gap widens beyond factory specifications, the ignition system struggles to maintain a consistent spark, resulting in a rough idle, reduced fuel economy, sluggish throttle response, and the dreaded P0300-series diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition service kit addresses these thermal and electrical failures head-on. The included direct-replacement ignition coils feature high-grade dielectric epoxy and upgraded copper windings, engineered to withstand the extreme thermal cycling of the AJ133 engine bay without breaking down. Operating at 12V with a measured 3-12KΩ resistance, they deliver maximum voltage directly to the plug. Paired with high-performance Iridium center-electrode spark plugs, this kit ensures a concentrated, high-intensity spark that significantly outperforms standard nickel or platinum alternatives. The plugs feature a 12mm thread, a 28mm reach, and are pre-gapped to 0.7-0.8mm to guarantee reliable combustion under high boost pressures, extending service intervals and fully restoring 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;\"\u003e2018-2022 Land Rover Range Rover Sport (5.0L V8)\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 Supercharged) \/ L494\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;\"\u003e518 hp \/ 461 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;\"\u003eUF-730, DX2312A366AC, LR035548, NGK93476\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2018 Land Rover Range Rover Sport 5.0L V8\u003c\/li\u003e\n  \u003cli\u003e2019 Land Rover Range Rover Sport 5.0L V8\u003c\/li\u003e\n  \u003cli\u003e2020 Land Rover Range Rover Sport 5.0L V8\u003c\/li\u003e\n  \u003cli\u003e2021 Land Rover Range Rover Sport 5.0L V8\u003c\/li\u003e\n  \u003cli\u003e2022 Land Rover Range Rover Sport 5.0L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Land Rover Precision\u003c\/h3\u003e\n\u003cp\u003eDesigned to meet the exacting standards of European luxury performance, this ignition package ensures perfectly timed combustion and eliminates persistent check engine lights (CELs), keeping your supercharged V8 running smoothly and efficiently.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50177350893816,"sku":"DS-E9LSU14H2","price":249.95,"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-sport-2018-2022-5-0l-v8-1.jpg?v=1787004600","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-land-rover-range-rover-sport-2018-2022-5-0l-v8","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
