Ignition Coil and Iridium Spark Plugs for Ford Fusion (2014-2020) 1.5L

Direct-Replacement Ignition Coil and Iridium Spark Plug Service Kit for 2014-2020 Ford Fusion

What it Does: Restores factory secondary ignition output, eliminates high-boost spark blowout, and resolves P0300-P0304 cylinder misfire codes across the direct-injected 1.5L EcoBoost platform.

The Stock Fusion Ignition Degradation

The direct-injected 1.5L EcoBoost engine subjects ignition coils and spark plugs to extreme cylinder pressures and tight thermal cycles. Over time, heat soak causes dielectric breakdown within factory epoxy insulation and micro-arcing across terminal boots. Simultaneously, high combustion temperatures erode standard nickel plug electrodes, increasing the spark gap and overtaxing the primary coil windings, leading to hesitation under boost, rough cold idles, and unburned fuel entering the catalytic converter.

The Engineering Solution

This comprehensive tune-up kit features four heavy-duty coil-on-plug assemblies engineered with high-purity internal copper windings and high-dielectric epoxy potting to withstand severe thermal expansion without internal shorts. Matched with four fine-wire iridium spark plugs, the assembly delivers consistent, concentrated spark kernel propagation under maximum turbo boost. Direct-fit OEM-style blade connectors ensure positive mechanical retention and zero harness modifications.
