Over duty cycles, factory coil-on-plug boots and internal insulation degrade from sustained thermal cycling in the recessed plug wells. This thermal degradation induces micro-arcing, core resistance drift, and high-rpm spark blowout under peak boost, resulting in rough cold starts, hesitations under load, and reduced fuel efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit features four direct-replacement ignition coils engineered with high-density copper windings and heavy-duty dielectric epoxy insulation to prevent voltage leakage and primary circuit breakdown. Paired with fine-wire iridium spark plugs, the assembly provides high thermal conductivity, corrosion resistance, and a consistent, concentrated spark kernel that withstands forced-induction pressures without quenching.\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;\"\u003e2019-2021 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;\"\u003e2.0L Turbo K20C4 \/ TC1, TC2\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;\"\u003e272 hp \/ 280 lb-ft\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;\"\u003eUF-781 \/ UF781\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2019 Acura RDX Base, Technology, A-Spec, Advance (2.0L L4 Turbo - TC1\/TC2)\u003c\/li\u003e\n  \u003cli\u003e2020 Acura RDX Base, Technology, A-Spec, Advance (2.0L L4 Turbo - TC1\/TC2)\u003c\/li\u003e\n  \u003cli\u003e2021 Acura RDX Base, Technology, A-Spec, Advance, PMC Edition (2.0L L4 Turbo - TC1\/TC2)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Acura Caliber Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet exact OEM electrical specifications, this direct-fit ignition kit drops directly into factory harnesses without throwing diagnostic trouble codes, delivering instant throttle response, smooth idle stability, and dependable power across all driving conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50452868006136,"sku":"DS-EV3C65LD9","price":111.95,"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-2019-2021-2-0l-1.jpg?v=1788723667","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-acura-rdx-2019-2021-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
