Over multiple heat cycles, the epoxy potting compound inside the OEM ignition coils begins to micro-crack, leading to internal arcing and voltage leaks. Simultaneously, standard or worn spark plugs suffer from electrode erosion, causing the spark gap to widen beyond factory tolerances. This combination forces the coils to work harder to jump the gap, significantly reducing secondary voltage output. For the Y50 chassis, this manifests as rough idling, hesitations under heavy load, diminished fuel economy, and eventual cylinder misfire codes (P0300 series) that disrupt the ECU’s air-fuel mapping.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis ignition coil and iridium spark plug package is engineered to surpass OEM specifications and stabilize the VQ35HR's combustion cycle. The ignition coils utilize upgraded primary and secondary copper windings with high-grade magnetic steel cores, maximizing spark energy and ensuring rapid charge times even at high RPMs. The housing features advanced thermal-resistant polymers and heavy-duty silicone boots that reject engine heat and prevent voltage leakage. Paired with laser-welded iridium center electrode spark plugs, this kit guarantees a consistent, hyper-focused spark. The ultra-fine iridium tip requires less voltage to bridge the gap, which drastically extends the lifespan of the coils while delivering complete air-fuel burns. This results in restored factory horsepower, smoother power delivery, and reliable cold starts in all conditions.\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;\"\u003e2009-2010 Infiniti M35\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 \/ Y50\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;\"\u003e303 hp \/ 262 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;\"\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\u003e2009 Infiniti M35 Base 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2009 Infiniti M35 X 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2010 Infiniti M35 Base 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2010 Infiniti M35 X 3.5L V6\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Infiniti Precision Caliber\u003c\/h3\u003e\n  \u003cp\u003eEngineered to match the high-revving precision of JDM V6 powerplants, this ignition service kit ensures your VQ35HR delivers the smooth, uncompromised power and reliability expected from a premier luxury sport sedan.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48234211410168,"sku":"DS-ECC2SSSQS","price":199.95,"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-m35-2009-2010-3-5l-1.jpg?v=1776100809","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-infiniti-m35-2009-2010-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
