Over extended duty cycles, factory coil-on-plug boots degrade from engine bay heat soak, resulting in micro-arcing and secondary voltage breakdown. Concurrently, high-boost forced induction accelerates electrode wear on standard plugs, causing premature gap widening. This degradation triggers intermittent misfire codes (P0300-P0304), rough idle cycles, tip-in hesitation under boost, and unburnt fuel washing down exhaust components.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit resolves secondary ignition collapse by pairing four heavy-duty coil packs with fine-wire iridium spark plugs. The coils utilize vacuum-impregnated epoxy potting around primary and secondary copper windings, sealing internal electronics against thermal degradation and vibration-induced open circuits. High-dielectric silicone boots resist carbon tracking into deep cylinder head spark plug wells. The included iridium spark plugs feature a minimal center electrode cross-section, requiring significantly lower ionization voltage to jump the gap under peak boost while preventing premature electrode erosion. This comprehensive drop-in package directly interchanges with \u003cstrong\u003eUF855\u003c\/strong\u003e hardware to guarantee factory ECU dwell-time compatibility.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4 Black Ignition Coils (Coil-on-Plug)\u003c\/li\u003e\n  \u003cli\u003e4 Iridium Fine-Wire Spark Plugs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e2021-2023 Ford Bronco\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;\"\u003e2.3L EcoBoost I4 \/ U725\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;\"\u003e300 hp \/ 325 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;\"\u003eUF855\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2021-2023 Ford Bronco 2.3L I4 (Base, Big Bend, Black Diamond, Outer Banks, Badlands)\u003c\/li\u003e\n  \u003cli\u003eCompatible with both 7-speed manual and 10-speed automatic transmissions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the U725 Bronco?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2021-2023 Ford Bronco equipped with the \u003cstrong\u003e2.3L EcoBoost\u003c\/strong\u003e inline-4 engine; it does not fit the 2.7L or 3.0L Nano V6 configurations.\u003c\/p\u003e\n\n\u003ch4\u003eShould dielectric grease be used during installation?\u003c\/h4\u003e\n\u003cp\u003eApplying a thin film of dielectric grease inside the lower silicone boot is highly recommended to seal out moisture and prevent boot adhesion to the spark plug ceramic.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Trailhead Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand rigorous off-camber trail abuse, severe towing loads, and continuous high-boost demands, this ignition package delivers the uncompromised combustion reliability your off-road rig requires.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67998815682808,"sku":"DS-E6Q2FYDIG","price":64.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-ford-bronco-2021-2023-2-3l-1.jpg?v=1794002316","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-spark-plugs-for-ford-bronco-2021-2023-2-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
