Nestled against the transverse VQ35DE, the rear bank (Bank 1) coils are subjected to severe, localized heat soak trapped against the firewall. Over time, the internal epoxy potting breaks down, leading to micro-cracking in the housing. This allows voltage to arc to the cylinder head rather than bridging the plug gap, resulting in under-load misfires (P0300-P0306 codes), hesitation during acceleration, and unburnt fuel damaging the catalytic converters. Concurrently, aging factory platinum plugs lose their gap tolerances, increasing electrical resistance and over-taxing the aging coils.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive 12-piece ignition service kit tackles the Z50's thermal challenges directly. The updated ignition coils feature high-dielectric epoxy resin and heavy-duty primary\/secondary copper wire windings to resist thermal breakdown and ensure consistent voltage output, even under extreme firewall heat. High-temperature silicone boots prevent flashover and effectively seal out moisture. Paired with high-performance iridium spark plugs, the system benefits from an ultra-fine center electrode that requires significantly less voltage to jump the gap. This reduces the electrical load on the new coils while generating a concentrated, highly stable spark front. The iridium alloy maintains precise gap specifications thousands of miles longer than standard materials, ensuring a complete combustion cycle and restoring the VQ35DE's factory throttle response.\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;\"\u003e2003-2007 Nissan Murano\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 \/ Z50\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;\"\u003e245 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\u003e2003 Nissan Murano 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2004 Nissan Murano 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2005 Nissan Murano 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2006 Nissan Murano 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2007 Nissan Murano 3.5L V6\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Nissan Caliber\u003c\/h3\u003e\n  \u003cp\u003eEngineered to maintain the renowned smooth power delivery of the VQ35DE, this ignition kit guarantees reliable daily driving, consistent torque for passing, and zero check engine lights on your daily commute.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48395529519352,"sku":"DS-EJN8FW893","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-nissan-murano-2003-2007-3-5l-v6-1.jpg?v=1778783992","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-nissan-murano-2003-2007-3-5l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
