Over time, the epoxy potting compound breaks down, leading to micro-cracking and internal secondary winding shorts. This heat soak results in weak spark delivery, manifesting as rough idling, hesitation under heavy throttle, and P0300-series misfire codes. Furthermore, standard platinum or aging spark plugs suffer from accelerated electrode erosion under the high-compression (11.0:1) environment of the VQ engine, increasing the gap and demanding higher firing voltage, which exponentially strains the already weakened OEM coils.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive ignition overhaul addresses thermal breakdown by utilizing upgraded coil housings formulated from high-dielectric polymer resins to resist heat soak and prevent voltage leakage. The primary and secondary copper windings are precision-wound to ensure a consistent, high-energy spark output through the entire RPM band. Paired with high-performance Iridium spark plugs, pre-gapped to precisely 0.8mm-0.9mm, this kit guarantees superior arc stability. Iridium’s ultra-high melting point (over 4,000°F) vastly outperforms traditional nickel and platinum variants, ensuring minimal electrode wear, highly efficient fuel atomization, and resistance to carbon fouling, thereby restoring optimal torque delivery and fuel economy.\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;\"\u003e2011-2013 Infiniti M37\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 \/ 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;\"\u003e330 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 \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2011 Infiniti M37 3.7L V6\u003c\/li\u003e\n    \u003cli\u003e2012 Infiniti M37 3.7L V6\u003c\/li\u003e\n    \u003cli\u003e2013 Infiniti M37 3.7L V6\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Infiniti Caliber\u003c\/h3\u003e\n  \u003cp\u003eEngineered for the demanding dynamics of Japanese luxury sedans, this ignition set ensures smooth, linear power delivery and eliminates frustrating CELs, keeping your VQ37VHR running flawlessly.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50137109037304,"sku":"DS-EAU2IEART","price":149.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-infiniti-m37-2011-2013-3-7l-v6-1.webp?v=1786381799","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-infiniti-m37-2011-2013-3-7l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
