Factory pencil coils suffer dielectric breakdown as internal epoxy resins degrade under constant heat soak, leading to high-voltage arcing, micro-cracking in the primary\/secondary windings, and hesitation under peak boost. Concurrently, factory spark plugs experience ground electrode erosion, widening the spark gap and forcing the coil to generate excessive kilovolt demands, which triggers intermittent P0300 through P0304 diagnostic trouble codes.\u003c\/p\u003e\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\u003cp\u003eThis complete ignition overhaul kit features four high-dielectric pencil ignition coils engineered to replace OEM number \u003cstrong\u003e9091902269\u003c\/strong\u003e (aftermarket \u003cstrong\u003eUF916\u003c\/strong\u003e), paired with four fine-wire iridium spark plugs. The coils utilize premium copper winding wire and reinforced silicone boots to withstand localized heat soak up to 260°C without insulation breakdown or current leakage. The matched iridium plugs feature laser-welded fine-wire center electrodes and trivalent metal plating for anti-fouling and anti-seizing properties. This ensures a low quenching effect, rapid flame kernel propagation, and stable spark timing across the entire 1,650 to 4,400 RPM torque plateau.\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\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;\"\u003e2018-2019 Lexus GS300\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;\"\u003e8AR-FTS \/ ARL10\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;\"\u003e241 hp \/ 258 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;\"\u003e9091902269, UF916, KIN133346TOP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2018 Lexus GS300 Base Sedan 4-Door 2.0L 1998cc I4 Turbo (8AR-FTS)\u003c\/li\u003e\n\u003cli\u003e2018 Lexus GS300 F Sport Sedan 4-Door 2.0L 1998cc I4 Turbo (8AR-FTS)\u003c\/li\u003e\n\u003cli\u003e2019 Lexus GS300 Base Sedan 4-Door 2.0L 1998cc I4 Turbo (8AR-FTS)\u003c\/li\u003e\n\u003cli\u003e2019 Lexus GS300 F Sport Sedan 4-Door 2.0L 1998cc I4 Turbo (8AR-FTS)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDoes this fit the ARL10 GS300?\u003c\/strong\u003e\u003cbr\u003eYes, this is a direct fit for the 2018-2019 Lexus GS300 equipped with the 8AR-FTS engine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre the iridium spark plugs pre-gapped for direct installation?\u003c\/strong\u003e\u003cbr\u003eYes, the spark plugs are pre-gapped to factory factory tolerance, though verification with a feeler gauge prior to installation is recommended.\u003c\/p\u003e\u003ch3\u003eThe Lexus Reliability Standard\u003c\/h3\u003e\u003cp\u003eEngineered to satisfy exacting Japanese luxury-sport tolerances, this ignition system delivers uncompromised combustion consistency, factory dwell angle compliance, and seamless ECU integration without throwing diagnostic trouble codes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50594617655544,"sku":"DS-E04SSM1GM","price":103.95,"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-gs300-2018-2019-2-0l-1.jpg?v=1790059196","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-lexus-gs300-2018-2019-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
