Ignition Coil and Iridium Spark Plugs for Ford Taurus X (2008-2009) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2008-2009 Ford Taurus X

What it Does: Restores precise secondary ignition voltage and consistent combustion across all six cylinders, resolving common misfire codes and rough running conditions.

The Stock Taurus X Ignition Degradation

The factory coil-on-plug boots and standard spark plugs on the transverse Duratec 35 V6 are vulnerable to severe thermal fatigue, particularly across the rear cylinder bank along the firewall. Prolonged heat soak causes micro-cracking in factory epoxy insulation, primary copper resistance increases, and spark plug gap erosion leads to dielectric breakdown. This results in intermittent cylinder misfires (P0300–P0306), unburnt hydrocarbon buildup, sluggish throttle response, and reduced fuel efficiency.

The Engineering Solution

This direct-replacement ignition pack upgrades your ignition secondary circuit using high-grade internal electrolytic copper windings encased in thermally stable, dielectric-rated housings. Precision blade terminals provide secure signal transfer without voltage drop. Paired with six fine-wire iridium spark plugs, this system lowers required firing voltage, provides a stable flame kernel under load, and resists fouling across harsh operating cycles.
