The original epoxy potting deteriorates and cracks, allowing moisture intrusion and secondary voltage leaks. This leads to weak spark delivery, noticeable hesitation under load, and eventual P0300-series misfire codes. Furthermore, standard-issue spark plugs experience electrode erosion past 60,000 miles. This erosion widens the spark gap, forcing the aging ignition coils to work harder to jump the gap, accelerating their internal failure and negatively impacting overall fuel efficiency.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis kit replaces the failure-prone OEM components with six high-dielectric epoxy ignition coils and six precision-gapped iridium spark plugs. The upgraded coils feature enhanced copper wiring and optimized primary\/secondary winding ratios to deliver higher voltage output and much faster recovery times between firing events. Paired with the ultra-fine iridium center electrodes—which require significantly less voltage to bridge the gap and boast exceptional resistance to heat and arc wear—this system ensures a highly concentrated, reliable spark. The direct result is a more complete fuel burn, smoother power delivery across the RPM range, and restored low-end torque essential for heavy load applications.\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;\"\u003e2011-2014 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;\"\u003e1GR-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;\"\u003e270 hp \/ 278 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;\"\u003e90919A2005, 673-1309, 23-0480, 5C1653\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2011 Toyota Tundra 4.0L V6\u003c\/li\u003e\n    \u003cli\u003e2012 Toyota Tundra 4.0L V6\u003c\/li\u003e\n    \u003cli\u003e2013 Toyota Tundra 4.0L V6\u003c\/li\u003e\n    \u003cli\u003e2014 Toyota Tundra 4.0L V6\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Toyota Towing Reliability\u003c\/h3\u003e\n  \u003cp\u003eEngineered for grueling work environments, these upgraded ignition components provide the reliability and durability required for consistent towing and hauling, ensuring your truck performs optimally without triggering diagnostic trouble codes under heavy operational stress.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48263148830968,"sku":"DS-EH76SQNPA","price":209.95,"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-2011-2014-4-0l-v6-1.jpg?v=1776746530","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-toyota-tundra-2011-2014-4-0l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
