Over time, high heat breaks down the internal primary and secondary copper windings, causing dielectric breakdown, micro-arcing, and intermittent cylinder misfires under load. Simultaneously, aged spark plug electrodes experience gap widening from electrical erosion, increasing secondary voltage demand and placing excessive strain on the driver transistors in the ignition system.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete 6-cylinder tune-up kit features heavy-duty coil-on-plug assemblies engineered with high-grade magnetic core steel, durable internal copper windings, and heat-resistant silicone boots to prevent flashover. Paired with fine-wire iridium spark plugs, the kit lowers ignition voltage requirements, delivers a highly focused spark kernel for complete combustion, and resists carbon fouling under severe thermal stress.\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;\"\u003e2004-2008 Lexus RX (3.3L V6)\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;\"\u003e3MZ-FE \/ XU30\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;\"\u003e230 hp \/ 242 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;\"\u003eUF267, 90919-02234, 90080-19016, IFR6T11\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004-2006 Lexus RX330 3.3L V6 (3MZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2006-2008 Lexus RX400h 3.3L V6 Hybrid (3MZ-FE)\u003c\/li\u003e\n  \u003cli\u003eInterchange: UF-267, 90919-02207, 9091902234, 9008019016, 9091902207, 19080-46020, C528, C1175\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Lexus Refinement Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet stringent Japanese luxury tolerances, this ignition system ensures factory-smooth power delivery, rapid cold-start ignition, and long-term misfire prevention without triggering check engine lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50451861602552,"sku":"DS-E1PYELOL2","price":100.95,"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-lexus-rx-2004-2008-3-3l-1.jpg?v=1788711383","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-lexus-rx-2004-2008-3-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
