Factory ignition coils undergo severe thermal stress due to the dense engine bay packaging and repetitive auto-start\/stop cycles inherent to the hybrid system. Over time, the OEM coil epoxy degrades, leading to micro-cracking and internal voltage leaks. This thermal breakdown causes weak spark energy, translating to rough idle, reduced fuel efficiency, hesitation during motor transition phases, and eventual engine misfires under load.\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 OEM thermal and voltage thresholds. The coils feature upgraded primary and secondary copper windings encased in high-temperature epoxy, ensuring consistent high-voltage output even during extreme heat cycling. The accompanying spark plugs utilize a laser-welded iridium center electrode and a platinum ground electrode, significantly reducing the required firing voltage while providing a stable, concentrated spark. This optimizes the air-fuel burn in the VQ35HR’s combustion chamber, ensuring a smooth hybrid transition, restoring lost power, and protecting the catalytic converters from unburned fuel saturation.\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;\"\u003e2012-2013 Infiniti M35h\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;\"\u003eVQ35HR \/ Y51\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;\"\u003e360 hp \/ 258 lb-ft (Combined 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\u003e2012 Infiniti M35h 3.5L V6 Hybrid\u003c\/li\u003e\n    \u003cli\u003e2013 Infiniti M35h 3.5L V6 Hybrid\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Infiniti Precision Standard\u003c\/h3\u003e\n  \u003cp\u003ePrecision matters on a JDM luxury chassis.
