The OEM coil boots are prone to heat degradation, hardening, and micro-cracking over time, leading to voltage leaks and subsequent cylinder misfires under load. Additionally, standard spark plug electrodes wear down, widening the plug gap. This increased gap forces the ignition coils to work harder to jump the arc, generating excess internal heat that eventually burns out the coil's primary windings and triggers P0300-series OBD2 misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive 16-piece tune-up kit directly addresses the 1UR-FE's ignition drop-off. The upgraded ignition coils feature high-temperature epoxy resin and advanced dielectric silicone boots to completely seal out moisture and resist engine bay heat soak. Internally, high-purity copper windings ensure a stronger, more consistent magnetic field for a hotter spark. Paired with the ultra-fine wire iridium spark plugs, which require significantly less firing voltage than traditional copper or platinum plugs, this system stabilizes the ignition arc. The iridium alloy provides exceptional resistance to oxidation and electrode wear, maintaining optimal gap spacing over high mileage while maximizing throttle response and fuel economy.\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;\"\u003e2010-2020 Lexus GX460\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;\"\u003e1UR-FE 4.6L V8 \/ J150\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;\"\u003e301 hp \/ 329 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;\"\u003eIC78053154J087810470408\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2010 Lexus GX460 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2011 Lexus GX460 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2012 Lexus GX460 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2013 Lexus GX460 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2014 Lexus GX460 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2015 Lexus GX460 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2016 Lexus GX460 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2017 Lexus GX460 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2018 Lexus GX460 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2019 Lexus GX460 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2020 Lexus GX460 4.6L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Lexus Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet the demanding durability standards of Lexus's body-on-frame platforms.
