Ignition Coil and Iridium Spark Plugs for Chrysler Pacifica (2005-2008) 3.8L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2005-2008 Chrysler Pacifica

What it Does: The ignition coil and iridium spark plug kit restores secondary ignition voltage and stable combustion on the 2005-2008 Pacifica to eliminate cylinder misfires, hesitation, and unburnt fuel waste.

The Stock Chrysler Pacifica Ignition Breakdown

The factory multi-tower coil pack on the CS platform operates in high-heat engine bay conditions. Over time, thermal cycling degrades the internal epoxy insulation and copper winding integrity, triggering internal short circuits, secondary voltage leaks, and intermittent P0300-P0306 diagnostic trouble codes. Compounding the issue, standard copper or platinum core plugs suffer rapid gap erosion on the 3.8L EGH pushrod engine. This excessive gap increases electrical resistance, overworking the ignition module and causing erratic combustion under load.

The Engineering Solution

This comprehensive refresh kit pairs a heavy-duty, direct-replacement coil block with six laser-welded iridium spark plugs. The replacement coil utilizes high-dielectric epoxy potting and optimized winding ratios to prevent voltage arcing and resist thermal fatigue. The included fine-wire iridium electrode plugs maintain stable gap tolerances up to 100,000 miles, requiring less ionization voltage while generating a broader, more efficient flame kernel. Engineered as a drop-in service solution corresponding to OE interchange UF305 and MPN KIN119797TOP.
