This thermal stress is prevalent in the engine bays of the 9th-generation Civic and early ILX models. As the dielectric insulating materials break down, high-voltage leaks occur, leading to weak spark output. Mechanically, this presents as under-load misfires (often throwing P0300 through P0304 trouble codes), erratic idle behavior, diminished throttle response, and unburned fuel entering the exhaust stream—which can prematurely degrade the catalytic converter. Worn factory spark plugs compound the issue by increasing the voltage demand on already weakened secondary coil windings.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive tune-up kit restores factory ignition performance through upgraded materials and precision engineering. The replacement ignition coils feature high-temperature epoxy and premium copper windings to resist heat soak and maintain consistent primary and secondary resistance values under heavy thermal loads. The blade-style terminals utilize precision-machined male connectors to guarantee secure, vibration-resistant seating with the factory female harness. Paired with iridium spark plugs, which feature an ultra-fine center electrode for superior ignitability and lower voltage requirements, this combination ensures a complete, powerful combustion event. The result is normalized fuel trim data, stabilized idle, restored 1.8L engine efficiency, and the complete elimination of ignition-related diagnostic trouble codes.\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;\"\u003e2012-2015 Honda, Acura Civic, ILX\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;\"\u003eR18Z1, R20A1 \/ FB2, FG3, DE1\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;\"\u003e143 hp \/ 129 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;\"\u003eUF672, 30520R1AA01, IC775\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2013-2015 Acura ILX l4 2.0L\u003c\/li\u003e\n    \u003cli\u003e2012-2015 Honda Civic l4 1.8L\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Honda, Acura Precision Standard\u003c\/h3\u003e\n  \u003cp\u003eDesigned for daily-driven reliability, restoring these crucial ignition components ensures precise i-VTEC engagement, eliminates frustrating check engine lights, and keeps your JDM-derived powertrain running flawlessly for its next major mileage milestone.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48238576697592,"sku":"DS-EF70JLLE9","price":149.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/Honda-Iridium-Ignition-2015.jpg?v=1776182723"},{"product_id":"ignition-coil-iridium-spark-plugs-for-acura-ilx-2016-2022-2-4l","title":"Ignition Coil \u0026 Iridium Spark Plugs for Acura ILX (2016-2022) 2.4L","description":"\u003ch2\u003eHigh-Output Ignition Coils \u0026amp; Iridium Spark Plugs for 2016-2022 Acura ILX (K24V7 \/ DE1)\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eDirect replacement ignition upgrade designed to restore spark energy, optimize combustion efficiency, and eliminate misfires.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch3\u003eThe Stock ILX Ignition Degradation\u003c\/h3\u003e\n\u003cp\u003eThe factory K24V7 ignition system is subjected to immense thermal stress due to the transverse engine layout and the inherently hot operating environment of the cylinder head.

Coupled with fine-wire iridium-tipped center electrodes and platinum ground pads, this kit lowers required ignition breakdown voltage, minimizes flame kernel quenching, and guarantees crisp throttle response across the power band.\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;\"\u003e2013-2015 Acura ILX (2.0L Models)\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\u003eR20A5\u003c\/strong\u003e \/ \u003cstrong\u003eDE1\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;\"\u003e150 hp \/ 140 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\u003e30520R1AA01\u003c\/strong\u003e, \u003cstrong\u003eC900\u003c\/strong\u003e, \u003cstrong\u003eKIN133363TOP\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\u003e2013 Acura ILX Base 2.0L L4 Gas (DE1)\u003c\/li\u003e\n  \u003cli\u003e2014 Acura ILX Base 2.0L L4 Gas (DE1)\u003c\/li\u003e\n  \u003cli\u003e2015 Acura ILX Base 2.0L L4 Gas (DE1)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the DE1 ILX?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2013-2015 Acura ILX equipped with the \u003cstrong\u003eR20A5\u003c\/strong\u003e 2.0L engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the included iridium spark plugs pre-gapped?\u003c\/strong\u003e\u003cbr\u003e Yes, the spark plugs come pre-gapped to factory specification, though checking clearance with a wire feeler gauge prior to installation is recommended.\u003c\/p\u003e\n\n\u003ch3\u003eThe Acura Engineering Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet stringent Japanese powertrain tolerances, this ignition system preserves clean-burning efficiency, smooth i-VTEC transitions, and dependable cold-start reliability mile after mile.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50594641215736,"sku":"DS-E9YXY7A2G","price":79.95,"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-ilx-2013-2015-2-0l-1.jpg?v=1790059229"}],"url":"https:\/\/performancechiptuning.com\/collections\/acura-ilx-ignition.oembed","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
