Ignition Coil + Spark Plugs for Ford Police Interceptor Sedan Utility (2013-2019) 3.5L Turbo

Direct-Fit Ignition Coil and Spark Plug Tune-Up Kit for 2013-2019 Ford Police Interceptor Sedan & Utility (D3 / U502)

What it Does: The ignition coil and spark plug kit replaces degraded factory ignition components on the 2013-2019 Ford Police Interceptor Sedan and Utility to eliminate spark blowout under boost, cure misfires, and restore combustion efficiency.

The Stock Ford Police Interceptor EcoBoost Ignition Breakdown

The twin-turbocharged 3.5L EcoBoost V6 operates under severe cylinder pressures and high thermal stress. 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.

The Engineering Solution

This 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.

Frequently Asked Questions & Fitment Warnings

Does this fit the D3 / U502 Taurus,Explorer?

Yes, this is a direct fit for the 2013-2019 Ford Police Interceptor Sedan and Utility equipped with the 3.5L EcoBoost V6 engine. Fits the 3.5L Turbo only. Not for the naturally aspirated 3.5L V6 or 3.7L V6 Police Interceptor Sedan, and not for 2018-2019 Sedan models. Not for the 3.7L V6 or 3.3L Police Interceptor Utility, and not for 2020 and newer Utility models.

What are the critical torque and installation guidelines for this kit?

Always install components on a cool engine, torque spark plugs to factory specification, and apply dielectric grease to the coil boot interiors without overtightening mounting fasteners.
