Located directly above the cylinder head, the OEM epoxy potting material undergoes severe heat cycling. Over time, this leads to micro-cracking within the internal primary and secondary coil windings, resulting in voltage leaks and dielectric breakdown. This manifests as random misfires, a flashing check engine light (CEL), unburnt fuel damaging the catalytic converters, and a noticeable hesitation under heavy engine loads.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition overhaul addresses these thermal vulnerabilities by utilizing upgraded internal components. The replacement coils feature high-temperature resistant epoxy and reinforced silicone boots to eliminate spark flashover and withstand the intense ambient heat radiating from the 3.5L V6 block. Paired with high-performance iridium spark plugs, the system requires significantly less firing voltage while providing a more concentrated and stable spark kernel. The ultra-fine iridium center electrode resists spark erosion, maintaining optimal gap tolerances for extended mileage, ensuring complete fuel atomization, smoother idle, and restored transient 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;\"\u003e2002-2006 Nissan Altima\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 \/ L31\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;\"\u003e250 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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002 Nissan Altima 3.5L V6\u003c\/li\u003e\n  \u003cli\u003e2003 Nissan Altima 3.5L V6\u003c\/li\u003e\n  \u003cli\u003e2004 Nissan Altima 3.5L V6\u003c\/li\u003e\n  \u003cli\u003e2005 Nissan Altima 3.5L V6\u003c\/li\u003e\n  \u003cli\u003e2006 Nissan Altima 3.5L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Nissan Precision Caliber\u003c\/h3\u003e\n\u003cp\u003eMaintaining the VQ-series V6 requires precision ignition hardware.
