Over time, radiant exhaust heat degrades the internal secondary windings and dries out the silicone boots. This leads to dielectric insulation breakdown, micro-arcing, and spark blowout under load. Simultaneously, factory spark plug ground electrodes erode, widening the gap and forcing deteriorating coils to pull excess primary amperage until complete failure triggers recurring P0300 through P0306 DTC misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis refresh kit replaces worn coil-on-plug modules with high-temp epoxy-potted ignition coils paired with pre-gapped Denso Platinum TT spark plugs (\u003cstrong\u003ePKH16TT\u003c\/strong\u003e). The replacement coils feature reinforced copper primary and secondary windings encased in heat-resistant thermoplastic housings that resist thermal fatigue and secondary voltage leakage. Denso's twin-tip platinum design utilizes a thin center electrode with a titanium-enhanced platinum ground pad, concentrating spark energy to reduce quenching and ensure rapid flame kernel propagation across the entire VTEC operating band.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e6 Ignition Coils\u003c\/li\u003e\n  \u003cli\u003e6 Denso Platinum TT Spark Plugs (PKH16TT)\u003c\/li\u003e\n\u003c\/ul\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;\"\u003e1999-2003 Acura TL, CL\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;\"\u003e3.2L J32A1, J32A2 \/ UA5, YA4\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;\"\u003e225-260 hp \/ 216-232 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;\"\u003eUF242, 4503, C1498, 2-50063, 30520P8EA01, 30520P8ES01, 30520P8FA01, C1221VC, 5094, 2505-98344, IGC0055, E745, 8N1, C1221, C1221-6, C1221DLGKIT, C1462, 82373, 49176, C-511, 89057937, E582C, 1IC105, 50063, 36-8148, 5092, 178-8303, 178-8379, 178-8380, 26346, GN10168, IC242, 352T, 8237\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\u003e1999-2003 Acura TL 3.2L (Base, Type-S)\u003c\/li\u003e\n  \u003cli\u003e2001-2003 Acura CL 3.2L (Base, Type-S)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the UA5 \/ YA4 TL,CL?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1999-2003 Acura TL and 2001-2003 Acura CL equipped with the 3.2L \u003cstrong\u003eJ32A1\u003c\/strong\u003e or \u003cstrong\u003eJ32A2\u003c\/strong\u003e engine; it is not a universal kit and does not fit 4-cylinder or 3.5L models.\u003c\/p\u003e\n\n\u003ch4\u003eShould I replace all coils and spark plugs simultaneously?\u003c\/h4\u003e\n\u003cp\u003eYes, replacing all six coils and plugs together ensures balanced primary resistance, equal spark duration across both cylinder banks, and prevents cascading misfires caused by mismatched aged components.\u003c\/p\u003e\n\n\u003ch3\u003eThe Acura Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet the precise demands of Acura's high-revving J-series V6, this direct replacement ignition kit ensures crisp throttle response, uniform idle stability, and uncompromising top-end power delivery through every gear shift.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67561479602424,"sku":"DS-ETWX50RLH","price":174.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-acura-tl-cl-1999-2003-3-2l-1.jpg?v=1790964004","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-spark-plugs-for-acura-tl-cl-1999-2003-3-2l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
