Over thousands of heat cycles, the factory ignition coil epoxy potting degrades, leading to micro-cracking in the housing. This thermal breakdown causes voltage leakage, which reduces the spark energy delivered to the cylinder. Simultaneously, the OEM platinum or standard iridium spark plugs experience electrode erosion. As the spark gap widens, the coils are forced to work harder to arc, creating a compounding failure loop that manifests as rough idling, hesitation under acceleration, and decreased fuel economy.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive ignition overhaul kit is engineered to withstand the extreme underhood temperatures of the VQ35DE platform. The updated ignition coils feature high-temperature dielectric epoxy and upgraded primary and secondary copper windings that ensure maximum voltage transfer without thermal breakdown. The included iridium spark plugs utilize an ultra-fine wire iridium center electrode and a tapered ground electrode to minimize quenching and provide a consistently dense spark. This material combination requires less firing voltage from the coils, directly extending coil lifespan while ensuring a complete fuel burn. By replacing the coils and plugs simultaneously, you re-establish baseline ignition timing, restoring factory throttle response, preventing unburnt fuel from damaging the catalytic converters, and ensuring reliable daily performance.\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;\"\u003e2011-2017 Nissan Quest\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;\"\u003eVQ35DE \/ E52\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;\"\u003e260 hp \/ 240 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\u003e2011-2017 Nissan Quest S 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2011-2017 Nissan Quest SV 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2011-2017 Nissan Quest SL 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2011-2014 Nissan Quest LE 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2015-2017 Nissan Quest Platinum 3.5L V6\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Nissan Reliability Standard\u003c\/h3\u003e\n  \u003cp\u003eBuilt to handle the rigorous daily cycles of family transport, this ignition upgrade ensures your JDM-derived VQ35DE engine maintains its signature smooth power delivery, optimized fuel economy, and steadfast reliability without throwing persistent check engine lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48234226745592,"sku":"DS-E2DCVM6ET","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-nissan-quest-2011-2017-3-5l-1.jpg?v=1776101253","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-nissan-quest-2011-2017-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
