Ignition Coil and Iridium Spark Plugs for Ford Fusion (2006-2009) 2.3L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2006-2009 Ford Fusion

What it Does: Restores factory secondary ignition voltage, eliminates cylinder misfires, and stabilizes idle by replacing deteriorated coil-on-plug packs and worn spark plugs.

The Stock Fusion Coil Breakdown

Factory ignition coils on the 2.3L engine frequently succumb to dielectric breakdown and thermal fatigue within the lower boot assembly due to sustained cylinder head heat. Over time, internal winding insulation degrades, leading to high secondary resistance, spark scatter, rough idle, and typical P0300 to P0304 misfire fault codes under heavy engine load.

The Engineering Solution

This complete tune-up kit features heavy-duty coil assemblies wound with premium internal copper wiring and sealed in high-dielectric epoxy to resist heat soak and voltage arcing. Paired with fine-wire iridium electrode spark plugs, this setup reduces ignition voltage demand, promotes rapid spark kernel development, and guarantees complete combustion across the entire RPM band.
