Over time, thermal cycling breaks down the OEM coil insulation and causes internal copper winding separation. This results in secondary voltage leakage, rough idle, hesitant acceleration, and persistent P0300-P0308 diagnostic trouble codes. Furthermore, worn factory plug gaps increase the required ionization voltage, accelerating coil pack failure under heavy load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement ignition kit includes eight reinforced coil-on-plug units built with premium internal copper windings, durable blade terminals, and high-temp silicone boots to prevent dielectric breakdown and arc-through. Matched with eight fine-wire iridium spark plugs, this setup reduces the voltage required to jump the gap, ensuring reliable cold starts, stable high-RPM spark delivery, and complete fuel atomization across both naturally aspirated and supercharged models.\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;\"\u003e2006-2009 Land Rover Range Rover Sport\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;\"\u003e4.2L AJ33S SC \/ 4.4L AJ41 NA V8 \/ L320\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;\"\u003e300-390 hp \/ 315-410 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;\"\u003eUF519, UF533, LR016999, AJ83415, 6R8312A366AA, C1678, 5C1735\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006-2009 Land Rover Range Rover Sport HSE 4.4L V8 Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e2006-2009 Land Rover Range Rover Sport Supercharged 4.2L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Land Rover Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact European electrical impedance tolerances, these components ensure clean ECU communication, prevent false misfire detection, and deliver smooth power without triggering Check Engine lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448274063608,"sku":"DS-EUXMU5BGX","price":124.95,"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-land-rover-range-rover-sport-2006-2009-4-2l-4-4l-1.jpg?v=1788638094","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-land-rover-range-rover-sport-2006-2009-4-2l-4-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
