Ignition Coil and Iridium Spark Plugs for Ford Fusion (2006-2012) 3.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2006-2012 Ford Fusion

What it Does: Restores factory ignition performance and eliminates secondary voltage leakage across all six cylinders by replacing aged coil packs and worn spark plugs with high-dielectric assemblies.

The Stock Fusion Coil Breakdown

In the transverse-mounted 3.0L V6 engine bay, high thermal stress—especially along the firewall-facing rear cylinder bank—degrades the factory coil epoxy and rubber boots over time. This continuous thermal cycling creates micro-fractures in the housing, leading to internal dielectric breakdown, high secondary resistance, and erratic spark delivery. Coupled with gap erosion on aged plugs, the ignition system suffers from hesitation under load, rough idle, and unburned fuel entering the exhaust stream.

The Engineering Solution

This complete 6-cylinder refresh kit pairs six heavy-duty ignition coils featuring reinforced internal copper windings and high-grade silicone boots with six fine-wire iridium spark plugs. The high-conductivity copper primary and secondary windings deliver stable, high-voltage discharge across the RPM band, while the corrosion-resistant blade terminals ensure zero-resistance contact. The fine-wire iridium center electrodes lower the required firing voltage, providing a concentrated spark kernel, clean flame propagation, and dependable resistance to fouling.
