Over multiple heat cycles, the OEM coil pack epoxy breaks down, leading to internal shorting, micro-cracking, and voltage leaks. Simultaneously, standard or aging spark plugs suffer from rapid electrode erosion. This manifests as high-RPM misfires, sluggish throttle response, unburnt fuel affecting the catalytic converters, and a fluctuating idle. Constant heat soak exacerbates these issues, causing increased resistance in the primary and secondary windings of the factory coil packs, fundamentally crippling spark delivery under load.\u003c\/p\u003e\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 12-piece ignition kit upgrades the combustion process by pairing high-output ignition coils with advanced iridium spark plugs. The coils utilize high-grade copper internal windings and specialized high-temperature dielectric epoxy to resist heat soak and maintain consistent voltage output under heavy mechanical loads. The included iridium spark plugs are significantly superior to standard nickel or platinum alternatives, featuring an ultra-fine center electrode that requires less voltage to jump the gap while providing a hotter, more concentrated spark front. Pre-gapped to precisely 0.8mm-0.9mm (0.031-0.035\"), these plugs ensure optimal flame kernel propagation. This synergistic combination guarantees complete combustion, restoring lost horsepower, maximizing fuel efficiency, and eliminating hesitation across the entire RPM band.\u003c\/p\u003e\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;\"\u003e2009-2020 Nissan 370Z\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;\"\u003eVQ37VHR \/ Z34\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;\"\u003e332 hp \/ 270 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;\"\u003e22448EY00A, UF-617, UF617\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2009-2020 Nissan 370Z Base 3.7L V6\u003c\/li\u003e\n\u003cli\u003e2009-2020 Nissan 370Z Touring 3.7L V6\u003c\/li\u003e\n\u003cli\u003e2009-2020 Nissan 370Z Sport 3.7L V6\u003c\/li\u003e\n\u003cli\u003e2009-2020 Nissan 370Z Nismo 3.7L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Nissan Caliber\u003c\/h3\u003e\n\u003cp\u003eFor the Z-car chassis, consistent power delivery and a smooth powerband are critical.
