The original epoxy potting cracks under repetitive thermal cycling, leading to secondary winding shorts, weak spark blow-out under load, and persistent P0300-series misfire codes. Additionally, standard copper or worn platinum plugs increase the resistance across the spark gap, forcing the coil packs to work harder and accelerating their inevitable failure.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis ignition overhaul kit provides a robust mechanical fix by utilizing high-dielectric epoxy resin within the coil housings to effectively resist heat soak. Internal copper wire windings ensure consistent secondary voltage output, crucial at the 2ZZ-GE's high RPM redline. Paired with fine-wire iridium spark plugs, required firing voltage drops significantly. Iridium's high melting point (over 4,000°F) prevents electrode erosion, ensuring a precise spark kernel. This translates to improved combustion efficiency, zero spark blowout, and a steady, predictable idle curve.\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;\"\u003e2000-2005 Toyota Celica, MR2 Spyder\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;\"\u003e1ZZ-FE, 2ZZ-GE \/ T230, W30\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;\"\u003e138-180 hp \/ 125-133 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;\"\u003e9091902262, UF247T\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2000-2005 Toyota Celica GT 1.8L I4\u003c\/li\u003e\n    \u003cli\u003e2000-2005 Toyota Celica GTS 1.8L I4\u003c\/li\u003e\n    \u003cli\u003e2000-2005 Toyota MR2 Spyder Base 1.8L I4\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Toyota Calibration Standard\u003c\/h3\u003e\n  \u003cp\u003eEngineered for high-revving Japanese domestic platforms, ensuring reliable power delivery, zero CELs, and consistent throttle response whether on the touge or the daily commute.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48345104056568,"sku":"DS-E937JDLRR","price":144.95,"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-celica-mr2-spyder-2000-2005-1-8l-i4-1.jpg?v=1778183293","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-toyota-celica-mr2-spyder-2000-2005-1-8l-i4","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
