As the OE coils experience thermal cycling and heat soak, the dielectric boots begin to crack, causing arcing and parasitic voltage loss. Concurrently, factory spark plugs experience electrode wear, widening the plug gap and demanding higher voltage output. This compound failure forces the ignition system to work harder, ultimately resulting in noticeable cylinder misfires, unburnt fuel entering the exhaust, diminished throttle response, and a drastic drop in overall engine efficiency.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis replacement ignition kit directly resolves the factory thermal vulnerabilities by utilizing upgraded, high-temperature epoxy resin within the coil windings to resist breakdown under extreme heat. The included ignition coils feature precision-wound copper stators that guarantee a consistent, high-energy spark across the entire RPM band. Paired with six premium iridium spark plugs, the system benefits from a micro-sized center electrode that concentrates spark energy, significantly lowering the voltage requirement while ensuring complete combustion. The iridium construction prevents gap erosion over high mileage, delivering stable idle dynamics, immediate throttle input, and restored factory power without triggering check engine lights.\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;\"\u003e2008-2013 Infiniti G37\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 \/ V36 \u0026amp; CV36\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;\"\u003e328 hp \/ 269 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;\"\u003eOE: 22448JA11C, UF617\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2008 Infiniti G37 3.7L V6\u003c\/li\u003e\n    \u003cli\u003e2009 Infiniti G37 3.7L V6\u003c\/li\u003e\n    \u003cli\u003e2010 Infiniti G37 3.7L V6\u003c\/li\u003e\n    \u003cli\u003e2011 Infiniti G37 3.7L V6\u003c\/li\u003e\n    \u003cli\u003e2012 Infiniti G37 3.7L V6\u003c\/li\u003e\n    \u003cli\u003e2013 Infiniti G37 3.7L V6\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Infiniti JDM Caliber\u003c\/h3\u003e\n  \u003cp\u003eDesigned to support the high-revving nature of the VQ-series V6, this ignition overhaul ensures restored power delivery, aggressive throttle response, and smooth idle stability crucial for top-tier Japanese sports platforms.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50256459989240,"sku":"DS-EKGQKIJT4","price":108.95,"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-g37-2008-2013-3-7l-1.jpg?v=1788039599","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-iridium-spark-plugs-for-infiniti-g37-2008-2013-3-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
