Over repeated thermal cycles, factory coils (OEM \u003cstrong\u003e90919-02216\u003c\/strong\u003e) experience epoxy potting degradation and micro-fractures within the coil bodies. This internal insulation breakdown leads to dielectric punch-through, spark scatter, and severe secondary voltage drop under load. Worn plug electrodes widen spark gaps, forcing aged coils to operate past their saturation threshold, triggering erratic idle, hesitations, and common P0300–P0306 misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service kit pairs three high-output waste-spark ignition coils with six precision-gapped spark plugs matched to factory thermal heat ranges. Each ignition coil features reinforced PBT thermoplastic housings and high-temperature epoxy potting to prevent dielectric failure from underhood heat soak. Premium copper windings deliver high-energy secondary arcs directly across the waste-spark paired cylinders, resisting electrical flashover and ensuring complete air-fuel combustion throughout the rev range.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e1998-2000 Lexus GS,SC\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\u003e2JZ-GE\u003c\/strong\u003e \/ \u003cstrong\u003eJZS160\u003c\/strong\u003e, \u003cstrong\u003eJZZ31\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;\"\u003e225 hp \/ 220 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\u003e90919-02216\u003c\/strong\u003e, \u003cstrong\u003eUF228\u003c\/strong\u003e, \u003cstrong\u003eC-847\u003c\/strong\u003e, \u003cstrong\u003eC1153\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1998-2000 Lexus GS 3.0L (GS300)\u003c\/li\u003e\n  \u003cli\u003e1998-2000 Lexus SC 3.0L (SC300)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the JZS160 and JZZ31 GS,SC?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1998-2000 Lexus GS,SC equipped with the \u003cstrong\u003e2JZ-GE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does this 6-cylinder kit only contain three ignition coils?\u003c\/strong\u003e\u003cbr\u003e The \u003cstrong\u003e2JZ-GE\u003c\/strong\u003e VVT-i utilizes a waste-spark ignition design where each dual-output coil fires two paired cylinders simultaneously, requiring only three coils for the entire six-cylinder engine.\u003c\/p\u003e\n\n\u003ch3\u003eThe Lexus Straight-Six Standard\u003c\/h3\u003e\n\u003cp\u003eThe naturally aspirated \u003cstrong\u003e2JZ-GE\u003c\/strong\u003e inline-six is celebrated for its factory balance and durability.
