Factory coils eventually suffer from primary winding breakdown and cracked epoxy housings, leading to voltage leaks and weak spark propagation. Simultaneously, standard plugs experience rapid electrode erosion under heavy towing loads. This degradation manifests as rough idling, reduced fuel economy, hesitation under load, and cylinder-specific misfire codes (P0300 through P0308) which severely cripple the towing capability of the naturally aspirated V8 platform.\u003c\/p\u003e\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition kit pairs high-output ignition coils with pre-gapped iridium spark plugs to provide a robust, long-term fix. The replacement coils are wound with premium heavy-gauge copper wiring and encapsulated in high-dielectric epoxy resin to resist extreme under-hood temperatures and prevent voltage flash-over. The accompanying spark plugs utilize an ultra-fine iridium center electrode combined with a laser-welded ground electrode, ensuring a concentrated, consistent spark that maximizes flame kernel expansion. This precise combustion event restores the stoichiometric efficiency of the 4.6L and 5.7L engines, stabilizing idle, eliminating hesitation, and optimizing power delivery when hauling heavy payloads.\u003c\/p\u003e\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;\"\u003e2007-2020 Toyota Tundra\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;\"\u003e1UR-FE, 3UR-FE \/ XK50\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;\"\u003e310-381 hp \/ 327-401 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;\"\u003eIC78053154J087810470408\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2007-2020 Toyota Tundra 4.6L V8 (1UR-FE)\u003c\/li\u003e\n\u003cli\u003e2007-2020 Toyota Tundra 5.7L V8 (3UR-FE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Toyota Towing Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt for the grueling demands of heavy hauling and off-road recovery, these ignition components restore the legendary durability and pulling power expected from Toyota's UR V8 platform.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50176902004984,"sku":"DS-ELE4M6BHJ","price":269.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-toyota-tundra-2007-2020-4-6l-5-7l-v8-1.jpg?v=1786998828","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-toyota-tundra-2007-2020-4-6l-5-7l-v8","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
