Over repeated heat cycles, OEM coil insulation breaks down, causing micro-fractures in the potting epoxy and dielectric punch-through. This loss of insulation allows secondary voltage to arc to ground rather than across the plug gap, causing hesitation, irregular idle, and prominent misfires under load. Concurrently, factory spark plug wear increases resistance, forcing the coils to run hotter and hastening failure.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand the demanding thermal envelope of the \u003cstrong\u003eZN6\u003c\/strong\u003e chassis, this complete ignition refresh kit pairs direct-fit pencil coils with fine-wire iridium spark plugs. The ignition coils feature high-grade magnetic core laminations and high-dielectric epoxy potting to resist thermal degradation and maintain consistent dwell timing. Paired with laser-welded fine-wire iridium plugs, the kit reduces ionization voltage requirements, producing an intense, focused spark kernel that optimizes flame-front propagation across direct and port injection cycles.\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;\"\u003e2015-2016 Scion FR-S\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\u003eFA20\u003c\/strong\u003e (\u003cstrong\u003e4U-GSE\u003c\/strong\u003e) \/ \u003cstrong\u003eZN6\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;\"\u003e200 hp \/ 151 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\u003eUF747\u003c\/strong\u003e, \u003cstrong\u003e22433AA700\u003c\/strong\u003e, \u003cstrong\u003e22433AA730\u003c\/strong\u003e, \u003cstrong\u003e22433AA650\u003c\/strong\u003e, \u003cstrong\u003e22433AA651\u003c\/strong\u003e, \u003cstrong\u003e22433AA652\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\u003e2015 Scion FR-S Base 2.0L H4 Gas (FA20)\u003c\/li\u003e\n  \u003cli\u003e2016 Scion FR-S Base 2.0L H4 Gas (FA20)\u003c\/li\u003e\n  \u003cli\u003e2016 Scion FR-S Release Series 2.0 2.0L H4 Gas (FA20)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the ZN6 FR-S?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2015-2016 Scion FR-S equipped with the \u003cstrong\u003eFA20\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the iridium plugs pre-gapped for this application?\u003c\/strong\u003e\u003cbr\u003e Yes, the spark plugs are factory-gapped to OEM specifications; do not use mechanical wedge tools on fine-wire iridium tips to prevent damaging the electrode.\u003c\/p\u003e\n\n\u003ch3\u003eThe Scion Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eMaintaining clean combustion all the way to the 7,400 RPM redline requires reliable secondary ignition delivery.
