Over time, internal epoxy insulation degrades, creating micro-fractures in the secondary winding that cause high-voltage dielectric breakdown and spark scatter under peak cylinder pressure. Simultaneously, factory spark plug ground electrodes erode from electrical discharge, widening the gap past factory clearance. This increases secondary resistance, leading to primary coil overload, intermittent misfires (DTC P0300 through P0306), unburned fuel fouling the catalytic converters, and sluggish transient throttle response on the \u003cstrong\u003eS190\u003c\/strong\u003e and \u003cstrong\u003eL10\u003c\/strong\u003e chassis.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement ignition service pack restores factory firing consistency using reinforced thermal magnetic laminations and copper core secondary windings engineered to resist thermal breakdown. The high-dielectric PBT housing prevents voltage leak-down and tracking down the boot. Paired with fine-wire iridium electrode spark plugs, this kit maintains a stable flame kernel under high cylinder pressures with significantly lower required breakdown voltage. Featuring standard OE-pin connectors, this set drops directly onto the factory harness without repinning or ECU recalibration.\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; 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;\"\u003e2007-2015 Lexus GS 350 \/ GS 450h (3.5L V6)\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;\"\u003e\n\u003cstrong\u003e2GR-FSE\u003c\/strong\u003e \/ \u003cstrong\u003eS190\u003c\/strong\u003e, \u003cstrong\u003eL10\u003c\/strong\u003e\n\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;\"\u003e306 hp \/ 277 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;\"\u003e\n\u003cstrong\u003eUF630\u003c\/strong\u003e, \u003cstrong\u003eUF507\u003c\/strong\u003e, \u003cstrong\u003eUF587\u003c\/strong\u003e, \u003cstrong\u003e90919-02256\u003c\/strong\u003e, \u003cstrong\u003e90919-A2005\u003c\/strong\u003e, \u003cstrong\u003e3473\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2007-2011 Lexus GS 350 3.5L V6 (S190 Chassis)\u003c\/li\u003e\n  \u003cli\u003e2007-2011 Lexus GS 450h 3.5L V6 Hybrid (S190 Chassis)\u003c\/li\u003e\n  \u003cli\u003e2013-2015 Lexus GS 350 3.5L V6 (L10 Chassis)\u003c\/li\u003e\n  \u003cli\u003e2013-2015 Lexus GS 450h 3.5L V6 Hybrid (L10 Chassis)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the S190 and L10 GS?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2007-2015 Lexus GS equipped with the \u003cstrong\u003e2GR-FSE\u003c\/strong\u003e 3.5L V6 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo these spark plugs require gapping prior to installation?\u003c\/strong\u003e\u003cbr\u003e No, the iridium fine-wire plugs come pre-gapped to factory specification, and mechanical gapping should be avoided to prevent damaging the fine iridium tip.\u003c\/p\u003e\n\n\u003ch3\u003eThe Lexus Performance Standard\u003c\/h3\u003e\n\u003cp\u003ePreserve the smooth, high-revving power delivery of your D-4S powertrain.
