In municipal and severe-duty pursuit fleets, extended engine idle hours accelerate thermal breakdown within the secondary winding insulation of OEM coil-on-plug units. Concurrently, forced induction erodes spark plug ground straps, widening the electrode gap beyond factory tolerances. This combination triggers dielectric breakdown, causing secondary voltage leakage, unburned fuel blow-by, hard starts, and intermittent cylinder misfires under peak boost. Degraded coils and out-of-spec plugs compromise throttle response and lower overall fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement ignition service pack utilizes high-dielectric epoxy housing and precision-wound copper secondary windings to maximize spark energy output and resist heat soak. Each coil features a factory-spec 3-pin connector and high-temperature silicone boot to prevent carbon tracking along the plug insulator. Paired with pre-gapped, heat-range-calibrated spark plugs tailored for pressurized direct-injection combustion chambers, this kit delivers consistent flame kernel propagation. Replacing all six coils and plugs simultaneously equalizes resistance across both cylinder banks, stabilizing fuel trim parameters and recovering lost torque across the rev range.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e6 Direct-Fit Ignition Coils\u003c\/li\u003e\n  \u003cli\u003e6 Boost-Calibrated 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 Police Interceptor Sedan \u0026amp; Utility\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 \/ \u003cstrong\u003eD3\u003c\/strong\u003e (Sedan), \u003cstrong\u003eU502\u003c\/strong\u003e (Utility)\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;\"\u003e\n\u003cstrong\u003eDG549\u003c\/strong\u003e, \u003cstrong\u003eSP534\u003c\/strong\u003e, 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\u003e2013-2017 Ford Police Interceptor Sedan 3.5L Turbo (3.5L V6 GAS DOHC Turbocharged EcoBoost)\u003c\/li\u003e\n  \u003cli\u003e2014-2019 Ford Police Interceptor Utility 3.5L Turbo (3.5L V6 GAS DOHC Turbocharged EcoBoost)\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 D3 \/ U502 Taurus,Explorer?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2013-2019 Ford Police Interceptor Sedan and Utility equipped with the \u003cstrong\u003e3.5L EcoBoost V6\u003c\/strong\u003e engine. \u003cstrong\u003eFits the 3.5L Turbo only.
