Heat soak causes internal epoxy resin breakdown, leading to micro-cracks in the coil housing. This results in voltage leaks, intermittent misfires, a rough idle, and sluggish throttle response. Additionally, standard OEM spark plugs experience rapid electrode erosion, widening the spark gap over time. A wider gap forces the ignition coils to work harder to jump the arc, compounding thermal stress on the coil packs and eventually leading to complete component failure and a flashing check engine light (CEL).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ignition coil and iridium spark plug kit resolves VQ25HR misfire issues by utilizing upgraded materials for superior thermal resistance and conductivity. The ignition coils feature high-grade dielectric epoxy and reinforced polymer housings that resist heat soak and prevent voltage leakage, ensuring maximum energy transfer. Paired with advanced iridium-tipped spark plugs, the system requires less overall voltage to generate a potent spark. The ultra-fine iridium center electrode resists electrical wear and oxidation, maintaining a precise spark gap over a significantly longer service life. This combination optimizes the air-fuel combustion sequence, resolving hesitation under load and preventing unburned fuel from reaching the exhaust tract.\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;\"\u003e2011-2012 Infiniti G25\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;\"\u003eVQ25HR (2.5L V6) \/ V36\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;\"\u003e218 hp \/ 187 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\u003e2011 Infiniti G25 Base Sedan 4-Door 2.5L V6\u003c\/li\u003e\n  \u003cli\u003e2011 Infiniti G25 Journey Sedan 4-Door 2.5L V6\u003c\/li\u003e\n  \u003cli\u003e2011 Infiniti G25 X Sedan 4-Door 2.5L V6\u003c\/li\u003e\n  \u003cli\u003e2012 Infiniti G25 Base Sedan 4-Door 2.5L V6\u003c\/li\u003e\n  \u003cli\u003e2012 Infiniti G25 Journey Sedan 4-Door 2.5L V6\u003c\/li\u003e\n  \u003cli\u003e2012 Infiniti G25 X Sedan 4-Door 2.5L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Infiniti Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet the precise tolerances of Japanese luxury vehicles, this ignition kit ensures your V36 chassis operates without intermittent misfires or erratic CEL triggers, delivering the smooth, linear power band expected from the VQ platform.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48234206363896,"sku":"DS-E3TNJ7INI","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-g25-2011-2012-2-5l-1.jpg?v=1776100674","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-infiniti-g25-2011-2012-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
