When the VCM shuts down specific cylinders to save fuel, the inactive cylinders experience rapid temperature fluctuations and oil bypass, leading to severe carbon fouling on the spark plug electrodes. Furthermore, the OEM coil packs suffer from thermal degradation due to their placement in the hot V6 engine bay. Over time, the internal epoxy potting breaks down, increasing electrical resistance. This results in weak spark delivery, intermittent cylinder misfires, sluggish throttle response, and unburnt fuel entering the exhaust stream, which can eventually damage the catalytic converters.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive performance ignition upgrade directly addresses the J35's thermal and electrical shortcomings. The replacement ignition coils feature upgraded copper wire windings and high-temperature silicone boots, maximizing dielectric strength and preventing voltage leaks under heavy load. Paired with ultra-fine wire iridium spark plugs, this kit significantly lowers the voltage requirement for a spark while delivering a concentrated, higher-intensity kernel. The iridium alloy offers exceptional resistance to oxidation and VCM-induced carbon fouling, ensuring consistent ignition across all operating conditions. By guaranteeing a complete combustion cycle, this setup maximizes the 3.5L's torque curve, eliminates hesitation, and stabilizes idle vacuum.\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;\"\u003e2013-2015 Acura RDX\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;\"\u003eJ35Z2 3.5L V6 \/ TB3 (FWD) \u0026amp; TB4 (AWD)\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;\"\u003e273 hp \/ 251 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;\"\u003eUF624, 30520RN0A01\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 RDX 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2014 Acura RDX 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2015 Acura RDX 3.5L V6\u003c\/li\u003e\n    \u003cli\u003eFitment Type: Direct Replacement\u003c\/li\u003e\n    \u003cli\u003ePlacement on Vehicle: Front\u003c\/li\u003e\n    \u003cli\u003eTerminal Type: Blade\u003c\/li\u003e\n    \u003cli\u003eTerminal Quantity: 3\u003c\/li\u003e\n    \u003cli\u003eKit Includes: 6 Performance Spark Plugs, 6 Ignition Coils\u003c\/li\u003e\n    \u003cli\u003eInterchange Part Numbers: UF624, 93175, 178-8482, IC727, 49020, U5304, C-889, 1IC450, 50174, 36-8165, 5095, 2505-484797, E1124, 30520RN0A01, C1665, 2-50174\u003c\/li\u003e\n    \u003cli\u003eOther Part Numbers: EBC1027, GN10426, 921-2154, SKUF624T, CUF603, 2IGC0436\u003c\/li\u003e\n    \u003cli\u003eSuperseded Part Numbers: 5C1681, 5C1722, IC727SB, UF624T, 673-2314, 23-0524, 52-2077\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Acura Precision Standard\u003c\/h3\u003e\n  \u003cp\u003eDesigned to exceed JDM factory specifications, this ignition overhaul ensures restored power, ultra-smooth VCM transitions, and long-term reliability without triggering a Check Engine Light (CEL).\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48262377963768,"sku":"DS-ECOXJ38AL","price":184.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-honda-rdx-2013-2015-3-5l-v6-1.jpg?v=1776721088","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-honda-rdx-2013-2015-3-5l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
