This persistent heat soak degrades the internal epoxy potting and compromises the primary and secondary copper windings. The result is parasitic voltage leakage, weakened spark blowout under heavy load, and progressive degradation of the spark plug electrodes, leading to rough idling, sluggish throttle response, and decreased combustion efficiency.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive ignition service kit features superior internal copper wiring and upgraded dielectric insulating materials to prevent voltage breakdown and resist thermal degradation. The redesigned coils deliver up to a 15% increase in spark energy, ensuring complete air-fuel combustion within the cylinders under high load. The matched iridium spark plugs utilize an ultra-fine center electrode, requiring lower firing voltage while providing a highly concentrated, stable spark core. This minimizes flame quenching, stabilizes the idle, and restores power delivery across the entire RPM band. The direct OE+ construction guarantees precise fitment, directly addressing factory heat-soak vulnerabilities.\u003c\/p\u003e\n  \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;\"\u003e2014-2023 Lexus RC\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;\"\u003e2GR-FKS, 2GR-FSE \/ XC10\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;\"\u003e311 hp \/ 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, 90919-02250, 90919-02256\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2014-2023 Lexus RC350 Base 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2014-2023 Lexus RC350 F Sport 3.5L V6\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Lexus Standard\u003c\/h3\u003e\n  \u003cp\u003eBecause the RC350 relies on precise fuel delivery and variable valve timing, maintaining peak ignition smoothness is critical for restoring factory power output, preserving throttle response, and ensuring long-term JDM reliability without triggering Check Engine Lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50062575993080,"sku":"DS-ED30BZBJ2","price":104.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-lexus-rc350-f-sport-2014-2023-3-5l-v6-1.jpg?v=1785169533","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-iridium-spark-plugs-for-lexus-rc350-f-sport-2014-2023-3-5l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
