Ignition Coil and Iridium Spark Plugs for Ford F-150 (2018-2020) 2.7L

High-Performance Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2018-2020 Ford F-150 (P552)

What it Does: The ignition coil and iridium spark plug kit refreshes the complete secondary ignition system on the 2018-2020 Ford F-150 to eliminate spark blowout, cure boost-induced misfires, and restore combustion efficiency.

The Stock Ford F-150 Ignition Weakness

High cylinder pressures and elevated thermal loads inherent to the twin-turbocharged 2.7L EcoBoost Nano engine cause rapid degradation of factory ignition components. Over time, engine bay heat cycling causes dielectric breakdown within factory coil boots, inviting secondary voltage arcing. Simultaneously, gap erosion on factory plugs increases required firing voltage. Under boost or heavy payload conditions, this degradation leads to spark quench, triggering check engine illumination, diagnostic trouble codes P0300 through P0306, sluggish acceleration, and reduced fuel economy.

The Engineering Solution

This comprehensive tune-up kit replaces the entire secondary circuit with components engineered to resist high-boost stress. The six ignition coils feature vacuum-potted epoxy windings to prevent internal shorting and thermal breakdown, paired with heat-resistant silicone boots that seal tightly over plug wells. The included fine-wire iridium spark plugs feature a high-melting-point center electrode requiring substantially lower firing voltage, maintaining a stable gap and ensuring complete flame-kernel propagation under peak cylinder pressure.

Frequently Asked Questions & Fitment Warnings

Does this fit the P552 F-150?

Yes, this is a direct fit for the 2018-2020 Ford F-150 equipped with the 2.7L EcoBoost Nano engine. Does not fit 2015-2017 F-150 2.7L models, which require UF773 style coils.

Is installation difficult?

It is a standard bolt-on job requiring basic hand tools: each coil secures via one retention bolt and connects directly to the OEM harness; torque plugs to factory spec and do not overtighten coil retainers.

The Ford Towing Standard

Delivering uninterrupted spark energy under sustained boost is mandatory for reliable towing and heavy-duty work, ensuring your truck maintains peak torque without stumbling under load.
