Packaged in a transverse V6 layout, the rear bank coils endure intense radiant heat trapped against the firewall. This persistent heat soak breaks down internal dielectric epoxy and copper windings, causing high electrical resistance. Combined with widening gaps on worn factory plugs, the system demands excessive voltage, leading to P0300-series misfires, hesitation under load, and reduced fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ignition service kit resolves V6 firing issues by upgrading both voltage delivery and spark generation. The upgraded coils utilize high-temperature dielectric epoxy and reinforced primary and secondary windings to withstand extreme thermal loads near the firewall. Paired with six performance Iridium spark plugs, the system ensures highly efficient combustion. Iridium's superior heat resistance permits a fine-wire center electrode, focusing electrical energy to create a robust spark kernel with lower secondary voltage demand. This ensures a complete fuel burn, restoring factory horsepower, smoothing out rough idling, and maximizing torque delivery.\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;\"\u003e2007-2015 Toyota Sienna\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;\"\u003e2GR-FE \/ XL20, XL30\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;\"\u003e266 hp \/ 245 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eInterchange Part Numbers\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e673-1309, 23-0480, 23-0525, 52-1894, 52-2092, C1601SPEC, EBC1039, CUF487, EBC1214, EBC1832, 26C1034, 90919A2005, C1601VC, 5C1653, IGC0176, C1596VC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2007-2015 Toyota Sienna 3.5L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Toyota Durability Standard\u003c\/h3\u003e\n\u003cp\u003eWhether you are handling daily carpool duties or towing a lightweight trailer, maintaining optimal combustion ensures this legendary JDM-engineered V6 delivers the reliable, long-term power and efficiency expected from the Toyota platform.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48263147487480,"sku":"DS-EA77S6H2A","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-sienna-2007-2015-3-5l-v6-1.jpg?v=1776746489","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-toyota-sienna-2007-2015-3-5l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
