The intense ambient heat generated by the transverse-mounted V6 design, specifically against the firewall bank, accelerates the breakdown of the coil housing's epoxy insulation. This leads to internal arcing, voltage leaks, and intermittent misfires, particularly under load. Concurrently, worn OEM spark plugs experience increased gap erosion, demanding higher firing voltages that further stress the failing coils, resulting in sluggish throttle response, elevated emissions, and reduced fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition kit utilizes upgraded primary and secondary copper windings within the coils to maximize magnetic flux and ensure a high-energy spark output. The external housings are molded from high-dielectric epoxy and thermal-resistant polymers to withstand the severe heat soak of the engine bay, effectively preventing internal arcing. Paired with high-performance Iridium spark plugs, the system provides an ultra-fine center electrode that requires less firing voltage while delivering a more concentrated, stable spark front. The Iridium alloy resists extreme combustion chamber temperatures and chemical erosion, guaranteeing a precise spark gap over extended mileage. Terminal connections feature OE-spec blade configurations for a true plug-and-play installation.\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;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2009-2014 Acura TL\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eJ35Z6 \u0026amp; J37A4 V6 \/ UA8, UA9\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e280-305 hp \/ 254-273 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF603, 93175, 30520R70A01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009 Acura TL 3.5L \u0026amp; 3.7L V6\u003c\/li\u003e\n  \u003cli\u003e2010 Acura TL 3.5L \u0026amp; 3.7L V6\u003c\/li\u003e\n  \u003cli\u003e2011 Acura TL 3.5L \u0026amp; 3.7L V6\u003c\/li\u003e\n  \u003cli\u003e2012 Acura TL 3.5L \u0026amp; 3.7L V6\u003c\/li\u003e\n  \u003cli\u003e2013 Acura TL 3.5L \u0026amp; 3.7L V6\u003c\/li\u003e\n  \u003cli\u003e2014 Acura TL 3.5L \u0026amp; 3.7L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Acura Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to restore Honda\/Acura's legendary J-Series reliability, this kit delivers the precise ignition timing and robust spark necessary for smooth power delivery and factory-spec efficiency, ensuring a CEL-free dash.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48262444646648,"sku":"DS-EJV4K7CPK","price":189.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-acura-tl-2009-2014-3-5l-3-7l-v6-1.jpg?v=1776721956","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-acura-tl-2009-2014-3-5l-3-7l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
