As the OEM epoxy resin ages and becomes brittle from continuous heat cycling, the coils develop micro-cracks that allow spark energy to arc directly to the cylinder head rather than jumping the plug gap. This energy loss manifests as high-RPM misfires, erratic idling, and reduced boost response under heavy engine load. Furthermore, aging factory plugs often suffer from gap erosion, exacerbating the load on the weakening coil packs and leading to incomplete combustion.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis ignition service kit resolves high-load misfires by combining six precision-wound coil-on-plug units with six iridium spark plugs. The replacement coils feature advanced thermal-shock resistant epoxy and high-grade copper windings, ensuring consistent resistance under severe engine bay temperatures. The included iridium spark plugs utilize an ultra-fine wire center electrode, requiring less voltage to ionize the gap while resisting electrode erosion. This combination ensures a high-intensity spark that resists blow-out under peak manifold pressure, restoring smooth power delivery, stabilizing idle characteristics, and maximizing fuel atomization for the legendary inline-six.\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;\"\u003e1996-1998 Toyota Supra\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;\"\u003e2JZ-GTE \/ JZA80\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;\"\u003e320 hp \/ 315 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;\"\u003e90919-02205, UF386\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e1996 Toyota Supra 3.0L 2JZ-GTE Turbo\u003c\/li\u003e\n    \u003cli\u003e1997 Toyota Supra 3.0L 2JZ-GTE Turbo\u003c\/li\u003e\n    \u003cli\u003e1998 Toyota Supra 3.0L 2JZ-GTE Turbo\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Toyota Tuning Caliber\u003c\/h3\u003e\n  \u003cp\u003eEngineered for the demands of the 2JZ platform, this ignition overhaul ensures reliable spark delivery to support both factory boost levels and elevated horsepower targets with unwavering JDM reliability.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50255529967864,"sku":"DS-EAEO4JG7W","price":139.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-toyota-supra-1996-1998-3-0l-1.jpg?v=1787984150","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-toyota-supra-1996-1998-3-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
