Positioned directly above the exhaust manifolds within a tightly packaged engine bay, the OEM epoxy potting compound breaks down after thousands of heat cycles. This thermal stress leads to internal primary and secondary winding shorts, resulting in weak spark output, intermittent high-RPM misfires, and deteriorating fuel economy. Furthermore, factory standard spark plugs suffer from accelerated electrode erosion under the VQ engine's high compression and aggressive Variable Valve Event and Lift (VVEL) mapping, leading to widened spark gaps and incomplete combustion.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive twelve-piece ignition kit addresses these thermal and electrical shortcomings. The upgraded ignition coils are constructed with high-dielectric epoxy and reinforced thermoplastic housings to resist severe heat soak and prevent voltage leaks, ensuring maximum energy transfer to the spark plug. Paired with these coils are high-performance iridium spark plugs, pre-gapped precisely between 0.8mm and 0.9mm. Iridium is significantly harder and more heat-resistant than standard nickel or platinum, allowing for a concentrated, ultra-fine center electrode. This design dramatically lowers the voltage requirement for spark creation, effectively eliminating spark blowout at high RPMs, stabilizing the idle, and restoring the crisp throttle response required by the 3.7L V6.\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 (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;\"\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\u003e2008-2013 Infiniti G37 Base 3.7L V6\u003c\/li\u003e\n    \u003cli\u003e2008-2013 Infiniti G37 Journey 3.7L V6\u003c\/li\u003e\n    \u003cli\u003e2008-2013 Infiniti G37 Sport 3.7L V6\u003c\/li\u003e\n    \u003cli\u003e2009-2013 Infiniti G37 X 3.7L V6\u003c\/li\u003e\n    \u003cli\u003e2011-2013 Infiniti G37 IPL 3.7L V6\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Infiniti Caliber\u003c\/h3\u003e\n  \u003cp\u003eEngineered for the rigorous demands of high-revving Japanese performance engines, this ignition package guarantees reliable power delivery, smooth acceleration, and consistent throttle response without triggering check engine lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50137103696120,"sku":"DS-EGS3BWDKN","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-g37-2008-2013-3-7l-v6-1.webp?v=1786381759","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-iridium-spark-plugs-for-infiniti-g37-2008-2013-3-7l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
