Over time, the factory ignition coil epoxy cracks and internal copper windings degrade, increasing electrical resistance and dropping voltage output. Coupled with standard spark plugs experiencing rapid electrode erosion, this combination leads to a weak spark kernel, pre-ignition events, sluggish throttle response, and the inevitable P0300 to P0306 misfire diagnostic trouble codes.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis ignition coil and iridium spark plug kit is engineered to exceed factory A35 and A36 specifications. The updated coils feature advanced high-temperature epoxy and highly conductive internal copper windings, minimizing voltage loss and preventing premature breakdown caused by relentless engine bay thermal cycling. Paired with precision laser-welded iridium center electrode spark plugs, this combination guarantees a concentrated, high-voltage spark kernel capable of piercing peak cylinder pressures. The ultra-fine iridium tip requires less firing voltage while providing superior resistance to high-heat gap erosion, ensuring stable combustion, restored low-end torque, and perfectly consistent ignition timing throughout the entire RPM band.\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;\"\u003e2009-2023 Nissan Maxima\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 \/ A35, A36\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;\"\u003e290-300 hp \/ 261 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;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2009-2023 Nissan Maxima S\u003c\/li\u003e\n    \u003cli\u003e2009-2023 Nissan Maxima SV\u003c\/li\u003e\n    \u003cli\u003e2009-2023 Nissan Maxima SL\u003c\/li\u003e\n    \u003cli\u003e2009-2023 Nissan Maxima SR\u003c\/li\u003e\n    \u003cli\u003e2009-2023 Nissan Maxima Platinum\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Nissan Reliability Caliber\u003c\/h3\u003e\n  \u003cp\u003eTailored for high-output VQ-powered sedans, this premium ignition service kit ensures restored power delivery, optimized fuel burn, and immediate throttle response.
