Ignition Coil and Iridium Spark Plugs for Ford Freestyle (2005-2007) 3.0L

Direct-Fit High-Output Ignition Service Kit for 2005-2007 Ford Freestyle

What it Does: Delivers a complete refresh of the primary and secondary ignition system by replacing degraded coil-on-plug packs and worn spark plugs to eliminate misfires and restore combustion efficiency.

The Stock Freestyle Ignition Coil Breakdown

The transverse-mounted 3.0L Duratec 30 engine subjects the rear cylinder bank to high thermal soak near the bulkhead. Over time, OEM coil boots degrade, and internal copper windings experience thermal breakdown of their insulating varnish. This leads to carbon tracking, secondary winding arc-through, high secondary resistance, and intermittent misfires under load (P0300–P0306 DTCs), which can overheat catalytic converters and strain PCM coil drivers.

The Engineering Solution

This direct-replacement ignition service pack utilizes heavy-duty oxygen-free copper primary and secondary windings encapsulated in high-dielectric epoxy resin to prevent internal flashover. Heat-stabilized silicone spark plug boots isolate secondary voltage surges, while the included fine-wire iridium center electrode spark plugs lower ignition voltage demand, resist gap erosion, and ensure rapid flame kernel propagation across all six combustion chambers.
