This aggressive heat soak breaks down the internal epoxy potting and primary winding insulation, leading to voltage leaks and weak spark delivery. Drivers typically experience random cylinder misfires (codes P0300 through P0306), hesitant throttle response under load, and significantly reduced fuel economy as unburned hydrocarbons exit through the exhaust system.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThese replacement ignition coils are engineered with high-dielectric epoxy and superior copper wire windings to resist thermal breakdown and ensure consistent voltage output even under extreme operating temperatures. The boot assemblies feature high-grade silicone to prevent moisture intrusion and electrical arcing. Paired with the included high-performance iridium spark plugs, which feature an ultra-fine center electrode for focused ignition and a remarkably high melting point, this kit delivers a robust, reliable spark. This translates to complete combustion, a smooth idle, and maximum energy transfer to the VQ35DE power plant without the typical lifespan limitations of standard copper or platinum alternatives.\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;\"\u003e2002-2004 Infiniti I35\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;\"\u003eVQ35DE \/ A33\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;\"\u003e255 hp \/ 246 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;\"\u003e224338J11C, 224488J100, 224488J110, 224488J111, 224488J115, C1406-6, IC479, IGC0006\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2002 Infiniti I35 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2003 Infiniti I35 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2004 Infiniti I35 3.5L V6\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Infiniti Caliber\u003c\/h3\u003e\n  \u003cp\u003eEngineered to match the smooth power delivery and refinement expected of Japanese luxury sedans, this ignition kit ensures your VQ35DE continues to operate with precision, delivering a robust power band without CEL interruptions or compromised drivability.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48395507925240,"sku":"DS-EDFGE627X","price":189.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-infiniti-i35-2002-2004-3-5l-v6-1.jpg?v=1778783754","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-infiniti-i35-2002-2004-3-5l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
