Over thousands of miles, the internal epoxy and secondary windings break down due to constant heat soak. This thermal degradation leads to internal voltage leaks, increasing primary resistance and causing intermittent misfires under load. Additionally, worn spark plugs widen the electrode gap, forcing the weakened coils to work harder to jump the gap. The result is a sluggish throttle response, reduced fuel efficiency, a rough idle, and the inevitable blinking Check Engine Light (CEL).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis kit upgrades the ignition system by utilizing precision-wound, high-durability copper wire within the coils, drastically improving thermal resistance and current transfer. By reinforcing the internal insulation, these coils prevent voltage bleed-off and maintain a consistent, high-energy output even under extreme engine bay temperatures. Paired with advanced iridium spark plugs, which feature an ultra-fine center electrode, the system achieves a highly concentrated spark. This combination yields a 15% increase in ignition energy and combustion efficiency over standard components. The iridium material inherently resists spark erosion, maintaining a precise gap over a much longer service life. Engineered to strict OE+ quality control standards, this setup is 100% factory-tested to drop in seamlessly and restore factory-level performance without triggering engine codes.\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;\"\u003e2005-2023 Lexus GS 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;\"\u003eGR-Series V6 (2GR\/3GR\/4GR) \/ S190, L10\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;\"\u003e207-341 hp \/ 186-280 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;\"\u003eUF507, UF630, UF487, C1596, E1007, E1087, IC587, 52-1889, 5C1653, 673-1309, 90919-02250, 90919-02256, 90919-C2001, 90919-A2003, 90919-A2005, 90919-T2004\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLexus GS250 V6 (2005-2023)\u003c\/li\u003e\n  \u003cli\u003eLexus GS300 V6 (2005-2023)\u003c\/li\u003e\n  \u003cli\u003eLexus GS350 V6 (2005-2023)\u003c\/li\u003e\n  \u003cli\u003eLexus GS450h V6 (2005-2023)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Lexus Standard\u003c\/h3\u003e\n\u003cp\u003eFor luxury JDM sedans, precision engineering is paramount.
