Over time, factory coil housings and internal windings develop micro-fractures, while silicone boots experience dielectric breakdown. Simultaneously, high cylinder pressures across the direct-injected \u003cstrong\u003e3.5L EcoBoost\u003c\/strong\u003e accelerate spark plug electrode erosion, expanding the gap beyond tolerance. This creates excessive electrical resistance, resulting in unburned fuel, hesitation under load, reduced fuel economy, and persistent misfire diagnostic trouble codes like P0300 through P0306.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit restores uniform secondary voltage output across both cylinder banks. The ignition coils feature premium magnetic copper wire windings isolated in high-dielectric epoxy resin to prevent internal shorting and resist extreme heat soak. Matched spark plugs provide the correct thermal heat range and ground electrode clearance necessary to prevent spark blowout under twin-turbo manifold pressure. Factory-style 3-pin terminations ensure seamless electrical continuity with the OEM harness without splicing or adaptation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e6x Direct-Fit Ignition Coils\u003c\/li\u003e\n  \u003cli\u003e6x Direct-Replacement Turbocharged 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;\"\u003e2013-2019 Ford Explorer\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;\"\u003e3.5L EcoBoost Twin-Turbo V6 \/ U502\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;\"\u003e365 hp \/ 350 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;\"\u003eDG549, SP534, UF646, IC749, 2505-484814, BL3Z-12029-C, E1146, 673-6300, 5C1871, SP537, SP580, SP528, CYFS-12-Y3\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\u003e2013-2015 Ford Explorer Sport 3.5L Turbo (3.5L V6 GAS DOHC Turbocharged)\u003c\/li\u003e\n  \u003cli\u003e2016-2019 Ford Explorer Sport 3.5L Turbo (3.5L V6 GAS DOHC Turbocharged)\u003c\/li\u003e\n  \u003cli\u003e2016-2019 Ford Explorer Platinum 3.5L Turbo (3.5L V6 GAS DOHC Turbocharged)\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 U502 Explorer?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2013-2019 Ford Explorer equipped with the \u003cstrong\u003e3.5L EcoBoost\u003c\/strong\u003e turbocharged engine. \u003cstrong\u003eFits 3.5L Turbo models only; it does NOT fit naturally aspirated 3.5L V6 models (Base, XLT, Limited) or 2.0L, 2.3L, 3.0L, and 3.3L engines.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWhat are the critical installation guidelines for this kit?\u003c\/h4\u003e\n\u003cp\u003eInstall components on a fully cooled engine, apply dielectric grease to the spark plug boot interiors, and torque the plugs to factory specifications without overtightening coil mounting hardware.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Towing \u0026amp; Utility Standard\u003c\/h3\u003e\n\u003cp\u003eWhen towing heavy loads or operating under sustained throttle, full ignition integrity is essential to maintain rated horsepower and exhaust gas temperatures on your heavy-duty Explorer.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67579068055800,"sku":"DS-EB7ABK99S","price":175.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-ford-explorer-2013-2019-3-5l-turbo-1.jpg?v=1791250292","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-spark-plugs-for-ford-explorer-2013-2019-3-5l-turbo","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
