Ignition Coil and Iridium Spark Plugs for Ford Fusion (2017-2019) 2.7L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2017-2019 Ford Fusion

Direct-Replacement Ignition Service Kit: Restores peak secondary voltage output, eliminates high-boost spark blowout, and resolves cylinder misfires across the 2.7L twin-turbocharged EcoBoost platform.

The Stock Fusion EcoBoost Ignition Degradation

Twin-turbo direct-injection engines like the 2.7L Nano subject ignition components to intense cylinder pressures and extreme engine bay heat soak. Over time, factory coil packs experience dielectric breakdown within the internal epoxy insulation and thermal fatigue across the copper windings. This leads to carbon tracking, erratic dwell timing, reduced secondary voltage, and noticeable misfires (DTCs P0300–P0306) under load, while worn factory plugs suffer gap erosion that taxes the ignition secondary circuit.

The Engineering Solution

This 6-cylinder refresh kit pairs six heavy-duty coil-on-plug units with six precision-gapped iridium spark plugs. Engineered with high-conductivity internal copper windings, durable thermoplastic housings, and OEM-spec blade terminals, these coils withstand thermal cycling without internal arching. The fine-wire iridium center electrodes provide concentrated spark energy and superior resistance to electrical erosion, maintaining crisp ignition kernel propagation and stable combustion under maximum boost pressure.
