This thermal degradation leads to voltage leaks, weak spark energy, and intermittent misfires, especially under heavy load or during cold starts. Furthermore, standard OEM spark plugs experience rapid electrode erosion over time. This erosion increases the gap width, forcing the ignition coils to work harder to jump the gap. This compounds the problem, resulting in sluggish throttle response, reduced fuel economy, and unburnt fuel washing down the cylinder walls.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ignition overhaul kit tackles voltage degradation by pairing high-output ignition coils with premium performance iridium spark plugs. The upgraded coils feature enhanced copper windings and high-temperature epoxy, increasing primary-to-secondary voltage transfer while actively resisting thermal breakdown. The accompanying iridium spark plugs utilize an ultra-fine center electrode, requiring lower firing voltage while delivering a hotter, more concentrated spark kernel. This optimized spark geometry ensures complete fuel burn, maximizing the 4.0L V6's power delivery, improving cold starting reliability, and providing long-term durability that far outlasts conventional copper or platinum alternatives. The combination restores factory torque capacity and stabilizes idle parameters.\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;\"\u003e2005-2011 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 4.0L V6 \/ XK30, XK40, 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;\"\u003e236 hp \/ 266 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;\"\u003e673-1308, 23-0485, SKIC039, TY1319484\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005 Toyota Tundra 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2006 Toyota Tundra 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2007 Toyota Tundra 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2008 Toyota Tundra 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2009 Toyota Tundra 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2010 Toyota Tundra 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2011 Toyota Tundra 4.0L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Toyota Workhorse Caliber\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle heavy payloads and daily towing duties, these upgraded ignition components ensure the rugged dependability and consistent low-end torque expected from the Toyota Tundra platform.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48268166004984,"sku":"DS-EM7POV7IG","price":175.99,"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-2005-2011-4-0l-v6-1.jpg?v=1776871054","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-toyota-tundra-2005-2011-4-0l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
