Over time, the thermal cycling degradation causes the epoxy inside the OEM coils to micro-crack, leading to voltage leaks and secondary ignition failures. Simultaneously, standard nickel or platinum spark plugs experience accelerated electrode wear under supercharged boost pressures, widening the gap beyond acceptable specifications. This degradation commonly manifests as rough idling, poor fuel economy, hesitation under load, and persistent P0300-series misfire codes, significantly compromising engine drivability.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis direct-replacement ignition coil and spark plug kit is engineered to withstand the harsh thermal and electrical demands of the 5.0L V8. The ignition coils feature a bolt-on, 3-pin design utilizing upgraded primary and secondary copper windings that deliver a stable 12V output. By minimizing resistance to a targeted 3-12KΩ range, these coils guarantee a rapid recharge cycle for consistent high-RPM performance. Paired directly with high-performance Iridium spark plugs, this kit ensures maximum durability. Iridium's extremely high melting point allows for a finer center electrode tip compared to traditional nickel, concentrating the spark for a more efficient burn. The plugs are pre-set to a precise 0.7mm-0.8mm gap, matching factory specifications to ensure perfect timing, while the 12mm thread diameter and 28mm reach guarantee proper indexing within the cylinder head.\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 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 \/ L405\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 5.0L V8\u003c\/li\u003e\n    \u003cli\u003e2019 Land Rover Range Rover 5.0L V8\u003c\/li\u003e\n    \u003cli\u003e2020 Land Rover Range Rover 5.0L V8\u003c\/li\u003e\n    \u003cli\u003e2021 Land Rover Range Rover 5.0L V8\u003c\/li\u003e\n    \u003cli\u003e2022 Land Rover Range Rover 5.0L V8\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Land Rover L405 Caliber\u003c\/h3\u003e\n  \u003cp\u003eDesigned for precise European electrical integration, this ignition package ensures a plug-and-play installation with zero check-engine lights, restoring the smooth, reliable power delivery expected from a premium supercharged luxury SUV.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50177348567288,"sku":"DS-EKQWY8P7K","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-2018-2022-5-0l-v8-1.jpg?v=1787004560","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-land-rover-range-rover-2018-2022-5-0l-v8","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
