Ignition Coil and Iridium Spark Plugs for Ford Taurus (2008-2012) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2008-2012 Ford Taurus

What it Does: Restores factory ignition energy, stabilizes secondary voltage output, and eliminates misfires across the cylinder bank on high-mileage naturally aspirated 3.5L V6 engines.

The Stock Taurus Secondary Ignition Breakdown

Factory coil-on-plug (COP) boots and primary/secondary windings on the transverse Duratec 35 undergo severe thermal cycling, especially under the rear intake plenum where ambient heat soak degrades the internal epoxy potting. Over time, micro-fractures in the coil housing cause high-voltage dielectric breakdown, leading to intermittent spark tracking, rough idle, hesitation under load, and catalyst-damaging misfires.

The Engineering Solution

This complete 6-cylinder ignition overhaul kit pairs heavy-duty coil packs with fine-wire iridium spark plugs for maximum thermal resilience and ignition consistency. The replacement coils feature high-conductivity internal copper windings insulated with premium epoxy resin to prevent secondary voltage leakage. Paired with corrosion-resistant blade terminals and high-dielectric silicone boots, this kit ensures a rapid, high-joule discharge across the iridium spark plug gaps to optimize flame-front propagation and restore fuel efficiency.
