Over time, factory coil boots and internal primary\/secondary copper windings break down due to thermal fatigue and dielectric breakdown. This degradation leads to high-RPM spark blowout, weak arc energy, and increased coil resistance. Concurrently, factory spark plug ground electrodes erode under high cylinder temperatures, widening the gap and forcing deteriorating coils to operate beyond their saturation threshold. The resulting incomplete burn triggers hesitation under acceleration, poor fuel economy, and persistent P0300 misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement ignition refresh pairs four high-output coil-on-plug units with fine-wire iridium spark plugs engineered to withstand high-boost direct-injection environments. The ignition pencil coils feature reinforced, heat-stabilized epoxy housings and low-resistance copper windings to guarantee reliable dielectric strength against high-heat electrical leakage. Matched with fine-wire iridium center electrodes with high melting points, the spark plugs provide superior flame kernel formation, resist gap erosion, and lower the required firing voltage. This ensures precise ignition timing, crisp throttle response, and robust misfire prevention across all operating ranges.\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;\"\u003e2021-2023 Land Rover Discovery\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;\"\u003e2.0L Turbo I4 (Ingenium AJ200P) \/ L462\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;\"\u003e296 hp \/ 295 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;\"\u003e5C2295, UF854, KIN135239TOP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2021 Land Rover Discovery S, S R-Dynamic (2.0L L4 Turbo P300)\u003c\/li\u003e\n  \u003cli\u003e2022 Land Rover Discovery S, S R-Dynamic (2.0L L4 Turbo P300)\u003c\/li\u003e\n  \u003cli\u003e2023 Land Rover Discovery S, S R-Dynamic (2.0L L4 Turbo P300)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the L462 Discovery?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2021-2023 Land Rover Discovery equipped with the 2.0L Ingenium AJ200P engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the iridium spark plugs pre-gapped for direct installation?\u003c\/strong\u003e\u003cbr\u003e Yes, the plugs are pre-gapped to factory specifications, though checking gap tolerance prior to installation is always recommended for forced-induction setups.\u003c\/p\u003e\n\n\u003ch3\u003eThe Land Rover Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet stringent European powertrain tolerances, these ignition components restore original factory ignition performance and prevent check engine lights (CELs) without requiring aftermarket ECU calibration.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50603740561656,"sku":"DS-EH5CQAB45","price":99.95,"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-discovery-2021-2023-2-0l-1.jpg?v=1790088143","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-land-rover-discovery-2021-2023-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
