Over time, engine bay thermal soak degrades the factory coil packs' internal epoxy insulation, leading to micro-arcing, secondary winding resistance breakdown, and spark blowout under load. Concurrently, factory plug gaps widen from electrode erosion, requiring higher secondary voltage that degraded \u003cstrong\u003e22448-JF00B\u003c\/strong\u003e coils cannot provide. This results in hesitation, stumbling under boost, P0300 multi-cylinder misfire trouble codes, and unburned fuel washing down cylinder walls.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis refresh kit provides six direct coil-on-plug units engineered with high-dielectric epoxy-filled windings and vulcanized heat-resistant boots to prevent voltage leakage and thermal breakdown. Paired with fine-wire iridium spark plugs featuring a 12mm thread, 14mm hex, and 26.5mm reach, the system substantially lowers required ignition voltage. The dense iridium center electrode maintains a tight 0.031-0.035 inch pre-set gap under relentless boost levels, delivering a potent, focused spark kernel that maximizes flame propagation across all combustion chambers of your \u003cstrong\u003eR35\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e6 Ignition Coils (Black, 3-pin blade connector, COP layout)\u003c\/li\u003e\n  \u003cli\u003e6 Pre-Gapped Iridium Spark Plugs (12mm thread, 14mm hex, 26.5mm reach)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2009-2021 Nissan GT-R\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eVR38DETT \/ R35\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e480-600 hp \/ 430-481 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e22448JF00B, 22448-JF00B, UF638\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009-2021 Nissan GT-R Base 3.8L V6 Twin Turbo\u003c\/li\u003e\n  \u003cli\u003e2009-2021 Nissan GT-R Premium 3.8L V6 Twin Turbo\u003c\/li\u003e\n  \u003cli\u003e2012-2020 Nissan GT-R Black Edition 3.8L V6 Twin Turbo\u003c\/li\u003e\n  \u003cli\u003e2014-2019 Nissan GT-R Track Edition 3.8L V6 Twin Turbo\u003c\/li\u003e\n  \u003cli\u003e2015-2021 Nissan GT-R Nismo 3.8L V6 Twin Turbo\u003c\/li\u003e\n  \u003cli\u003e2020-2021 Nissan GT-R 50th Anniversary Edition 3.8L V6 Twin Turbo\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the R35 GT-R?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2009-2021 Nissan GT-R equipped with the \u003cstrong\u003eVR38DETT\u003c\/strong\u003e twin-turbo engine across all trims and transmission types.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to gap the spark plugs or apply dielectric grease prior to installation?\u003c\/h4\u003e\n\u003cp\u003eThe plugs come pre-gapped to 0.031-0.035 inches, but verifying clearance before installation is advised; a light film of dielectric grease on the coil boot interior is recommended to ensure thermal isolation and simplify future servicing.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan High-Performance Standard\u003c\/h3\u003e\n\u003cp\u003eConstructed to endure the extreme combustion temperatures and rigorous high-RPM operation typical of VR38DETT motorsport demands, this complete ignition refresh ensures stable high-boost combustion without spark scatter or misfire-induced limp modes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":68083577815288,"sku":"DS-ELB8P8CKR","price":105.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-and-iridium-spark-plugs-for-nissan-gt-r-2009-2021-3-8l-1.jpg?v=1794528425","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-nissan-gt-r-2009-2021-3-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
