Over mileage cycles, the factory secondary winding insulation breaks down within the coil packs, resulting in high-voltage micro-arcing and boot carbon tracking. Simultaneously, the factory spark plug gap erodes from sustained turbo boost, demanding higher ionization voltage than aging coils can deliver. This ignition degradation triggers P0300 through P0306 DTC misfire codes, sudden hesitation during transient boost ramp-up, sluggish throttle response, and unburnt fuel washing down cylinder walls.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement kit replaces all six coil-on-plug units and matched spark plugs simultaneously to rebalance spark energy across both cylinder banks. Each ignition coil features high-dielectric epoxy resin encapsulation to withstand cyclic thermal expansion without developing internal dielectric breakdown, coupled with heat-stabilized silicone boots that isolate high-kV energy from the plug wells. The direct-fit 3-pin connectors maintain factory harness retention without modification. The companion spark plugs come pre-calibrated to the exact heat range and electrode gap required for forced-induction cylinder pressures, resisting pre-ignition and quenching under peak commercial boost levels.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e6 Ignition Coils\u003c\/li\u003e\n  \u003cli\u003e6 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;\"\u003e2015-2020 Ford Transit\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 V6 \/ V363\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;\"\u003e310 hp \/ 400 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\u003e2015-2020 Ford Transit-150 3.5L Turbo (3.5L V6 GAS DOHC Turbocharged EcoBoost)\u003c\/li\u003e\n  \u003cli\u003e2015-2020 Ford Transit-250 3.5L Turbo (excluding 2018 Transit-250 PTV)\u003c\/li\u003e\n  \u003cli\u003e2015-2020 Ford Transit-350 3.5L Turbo\u003c\/li\u003e\n  \u003cli\u003e2015-2020 Ford Transit-350 HD 3.5L Turbo\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 V363 Transit?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2015-2020 Ford Transit equipped with the \u003cstrong\u003e3.5L EcoBoost\u003c\/strong\u003e engine. \u003cstrong\u003eFits the 3.5L Turbo only.
