Over time, internal epoxy insulation breaks down and lower boot silicone hardens, creating micro-fractures that induce dielectric voltage leakage and secondary arc-over. Combined with worn spark plug electrode gaps, this deterioration results in high-RPM spark blowout during i-VTEC engagement, sluggish transient response, unburned hydrocarbons, and P0300–P0304 cylinder misfire fault codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement kit resolves secondary ignition drop-off by pairing heavy-duty coil packs with fine-wire iridium spark plugs. The coil assemblies are engineered with high-conductivity electrolytic copper primary and secondary windings potted in high-dielectric epoxy, ensuring maximum resistance to heat soak and internal arc-through. Direct-fit blade terminals and factory-matched electrical connectors eliminate signal resistance. The companion iridium spark plugs feature high-melting-point fine-wire center electrodes that require lower strike voltage, promoting rapid flame kernel growth and preventing carbon fouling under variable valve timing transitions.\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 TSX 2.4L\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;\"\u003eK24Z3 \/ CU2 (Sedan), CW2 (Sport Wagon)\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;\"\u003e201 hp \/ 172 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number \/ Interchange\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF602, 30520R40007, 30520RL5A01, C-804, C1662, E1102, IC692, 52-2074, 5C1719\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2009 Acura TSX:\u003c\/strong\u003e 2.4L L4 Gas DOHC (Base)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2010 Acura TSX:\u003c\/strong\u003e 2.4L L4 Gas DOHC (Base)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2011 Acura TSX:\u003c\/strong\u003e 2.4L L4 Gas DOHC (Base, Sport Wagon)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2012 Acura TSX:\u003c\/strong\u003e 2.4L L4 Gas DOHC (Base, Special Edition, Sport Wagon)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2013 Acura TSX:\u003c\/strong\u003e 2.4L L4 Gas DOHC (Base, Special Edition, Sport Wagon)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2014 Acura TSX:\u003c\/strong\u003e 2.4L L4 Gas DOHC (Base, Special Edition, Sport Wagon)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Acura Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet tight tolerances for high-revving Japanese powertrains, this complete ignition package maintains linear dwell times and uninterrupted spark energy all the way to the 7,100 RPM redline, preserving stoichiometric fuel trim balance and factory-calibrated power delivery.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448864510200,"sku":"DS-EUEVCFPLR","price":99.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-and-iridium-spark-plugs-for-acura-tsx-2009-2014-2-4l-1.jpg?v=1788662379","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-acura-tsx-2009-2014-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
