Over extended service intervals, OEM plug gaps widen from standard erosion, increasing the required ionization voltage. This extra electrical resistance accelerates internal primary and secondary winding breakdown inside the coil packs, causing rough idle, reduced throttle response, and degraded fuel economy under variable cylinder management (VCM) transitions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive kit features high-grade electrolytic copper internal windings engineered to maintain stable magnetic saturation and deliver consistent kilovolt output across all engine speeds. Reinforced thermoplastic PBT housings prevent thermal cracking and arc-over, while precision direct-fit blade terminals ensure secure electrical contact. Paired with fine-wire iridium spark plugs, the assembly lowers ignition voltage demand, stabilizes flame kernel development, and guarantees reliable cold starts and smooth high-RPM power delivery.\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;\"\u003e3.5L J35Z2 V6 \/ TB3 (FWD), 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;\"\u003eUF603, UF-603, 673-2311, 610-50158, 610-58733, 178-8379, C1624, 30520R70A01, 30520R70S01, 5C1681\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 Base \/ Technology Package (3.5L V6 - Gas)\u003c\/li\u003e\n  \u003cli\u003e2014 Acura RDX Base \/ Technology Package (3.5L V6 - Gas)\u003c\/li\u003e\n  \u003cli\u003e2015 Acura RDX Base \/ Technology Package (3.5L V6 - Gas)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Acura Engineering Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet exact factory tolerances, this complete ignition package ensures clean, misfire-free operation through all VTEC engagement zones without triggering check engine lights or hesitation under load.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448481976568,"sku":"DS-EQXF9AWZH","price":105.95,"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-rdx-2013-2015-3-5l-1.jpg?v=1788646969","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-acura-rdx-2013-2015-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
