Over time, heat exposure degrades the internal epoxy potting and secondary copper windings inside the OEM coils (part numbers \u003cstrong\u003e9091902215\u003c\/strong\u003e and \u003cstrong\u003e9008019012\u003c\/strong\u003e), resulting in micro-arcing, internal resistance spikes, and insulation breakdown. Paired with aged, gap-widened spark plugs, this delivers weak ignition energy, triggering common cylinder misfire codes (P0300–P0306), unburnt hydrocarbon accumulation in the catalytic converters, reduced fuel efficiency, and hesitant acceleration under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition refresh replaces tired factory components with high-dielectric coil-on-plug modules and premium fine-wire iridium spark plugs. The replacement coils feature reinforced thermoplastic housings filled with high-purity polyurethane resin to seal against moisture ingress and prevent thermal arc-through. Internal silicon steel magnetic cores and high-conductivity copper wiring ensure fast rise times and stable saturation across the entire operating range of the \u003cstrong\u003e1MZ-FE\u003c\/strong\u003e engine. Matched with laser-welded iridium spark plugs offering high melting points and anti-fouling geometry, this kit resolves erratic idle conditions, restores factory ignition curves, and promotes optimal flame front propagation.\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; margin-bottom: 20px;\"\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;\"\u003e1999-2003 Toyota Solara\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;\"\u003e\n\u003cstrong\u003e1MZ-FE\u003c\/strong\u003e \/ \u003cstrong\u003eXV20\u003c\/strong\u003e\n\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;\"\u003e200 hp \/ 214 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;\"\u003e\n\u003cstrong\u003eUF155\u003c\/strong\u003e, \u003cstrong\u003eCUF155\u003c\/strong\u003e, \u003cstrong\u003e9091902215\u003c\/strong\u003e, \u003cstrong\u003e9008019012\u003c\/strong\u003e, \u003cstrong\u003eGN10218\u003c\/strong\u003e, \u003cstrong\u003e5C1488\u003c\/strong\u003e, \u003cstrong\u003e1788235\u003c\/strong\u003e, \u003cstrong\u003e88921336\u003c\/strong\u003e, \u003cstrong\u003eE588\u003c\/strong\u003e, \u003cstrong\u003eC575\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1999 Toyota Solara SE \/ SLE 3.0L V6 (1MZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2000 Toyota Solara SE \/ SLE 3.0L V6 (1MZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2001 Toyota Solara SE \/ SLE 3.0L V6 (1MZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2002 Toyota Solara SE \/ SLE 3.0L V6 (1MZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2003 Toyota Solara SE \/ SLE 3.0L V6 (1MZ-FE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the XV20 Solara?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1999-2003 Toyota Solara equipped with the \u003cstrong\u003e1MZ-FE\u003c\/strong\u003e 3.0-liter V6 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo these iridium spark plugs require manual gapping prior to installation?\u003c\/strong\u003e\u003cbr\u003e No, these iridium spark plugs arrive pre-gapped to factory tolerance; attempting to manually gap them can fracture the brittle laser-welded iridium center electrode.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Caliber Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to deliver smooth, vibration-free operation, this direct-replacement ignition setup restores the factory-tuned torque curve and linear throttle response that defines classic Japanese V6 touring platforms.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50594053357816,"sku":"DS-EURDYY9IA","price":74.95,"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-toyota-solara-1999-2003-3-0l-1.jpg?v=1790056420","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-toyota-solara-1999-2003-3-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
