Ignition Coil and Iridium Spark Plugs for Ford Fusion (2010-2020) 2.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2010-2020 Ford Fusion

What it Does: Restores factory secondary ignition voltage and combustion efficiency by replacing worn coil-on-plug assemblies and fouled spark plugs in one complete service matched set.

The Stock Fusion Ignition Degradation

The 2.5L Duratec engine subjects factory coil packs to persistent thermal cycling and dielectric breakdown. Over time, high cylinder-head operating temperatures cause epoxy micro-cracking within OEM coil housings, leading to secondary voltage leakage, carbon tracking, and intermittent misfires under load. Concurrently, standard nickel or worn factory plugs suffer electrode erosion, widening the spark gap and placing elevated electrical resistance on the primary winding circuit, which manifests as rough idle, sluggish throttle response, and degraded fuel economy.

The Engineering Solution

This direct-replacement ignition service pack utilizes heavy-duty copper primary and secondary windings encased in high-dielectric epoxy resin to prevent internal flashover and resist thermal degradation. The coil-on-plug boots feature heat-resistant silicone and corrosion-resistant blade terminals for positive contact retention. Paired with high-temperature fine-wire iridium spark plugs, the kit ensures low required firing voltage, superior flame kernel expansion, consistent ignition under all engine loads, and long-term durability backed by a lifetime warranty.
