OEM coils frequently suffer from internal winding breakdowns and cracked epoxy potting, leading to voltage leaks and resistance spikes. Simultaneously, standard or worn factory spark plugs fail to maintain a consistent electrode gap under the 1AR-FE's engine load. This causes partial misfires, hesitation during acceleration, unburned fuel dumping into the exhaust manifold, and a noticeable drop in overall fuel economy and throttle response.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition overhaul addresses these thermal and electrical vulnerabilities head-on. The upgraded ignition coils are wound with high-conductivity copper and sealed in premium, heat-resistant dielectric epoxy to prevent voltage bleed and thermal arcing. Paired with performance Iridium spark plugs, this kit delivers a highly concentrated, ultra-fine spark. The iridium alloy boasts a drastically higher melting point than standard materials, ensuring gap stability and resisting electrode erosion even under severe thermal stress. This translates to an immediate restoration of torque, superior fuel atomization, and reliable cold starts regardless of environmental conditions.\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;\"\u003e2011-2013 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;\"\u003e1AR-FE \/ ASL30\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;\"\u003e187 hp \/ 186 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;\"\u003e673-1309, 23-0480, 23-0525, 52-1894, 52-2092, 90919A2005, 5C1653, IGC0176\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 Sienna 2.7L I4\u003c\/li\u003e\n  \u003cli\u003e2012 Toyota Sienna 2.7L I4\u003c\/li\u003e\n  \u003cli\u003e2013 Toyota Sienna 2.7L I4\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Toyota Durability Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned to meet the stringent demands of Japanese engineering, this ignition package ensures long-lasting durability and consistent power delivery, keeping your high-occupancy daily driver completely CEL-free and running at peak factory efficiency.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48266412261624,"sku":"DS-EK7KOT5K1","price":144.95,"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-2011-2013-2-7l-i4-1.jpg?v=1776814699","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-toyota-sienna-2011-2013-2-7l-i4","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
