Ignition Coil + Spark Plugs for Ford Explorer (2013-2019) 3.5L Turbo

Direct-Replacement Ignition Coil and Spark Plug Tune-Up Kit for 2013-2019 Ford Explorer (U502)

What it Does: The ignition coil and spark plug kit replaces deteriorated secondary ignition components on the 2013-2019 Explorer to eliminate spark blowout, eradicate misfires, and restore combustion efficiency under boost.

The Stock Ford Explorer Ignition Breakdown

Under sustained boost, the twin-turbocharged transverse engine bay of the U502 chassis subjects ignition components to intense thermal stress. 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 3.5L EcoBoost 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.

The Engineering Solution

This 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.

Frequently Asked Questions & Fitment Warnings

Does this fit the U502 Explorer?

Yes, this is a direct fit for the 2013-2019 Ford Explorer equipped with the 3.5L EcoBoost turbocharged engine. Fits 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.

What are the critical installation guidelines for this kit?

Install 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.

The Ford Towing & Utility Standard

When 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.
