Ignition Coil and Iridium Spark Plugs for Chrysler Pacifica (2004-2006) 3.5L

Direct-Replacement Ignition Kit for 2004-2006 Chrysler Pacifica

What it Does: Refreshes the primary and secondary ignition circuitry by replacing tired coil-on-plug modules and worn spark plugs to eliminate misfires and restore factory combustion efficiency.

The Stock Pacifica Secondary Ignition Breakdown

The 3.5L SOHC V6 in the CS-chassis Pacifica places the ignition coils deep inside recessed cylinder head wells. Over extended thermal cycles, the factory epoxy insulation breaks down and internal secondary winding resistance drifts out of specification. This leads to dielectric breakdown, high-voltage flashover at the boot, unburned fuel entering the exhaust stream, and recurring P0300-P0306 misfire trouble codes under heavy throttle or cruise load.

The Engineering Solution

This complete ignition kit features six heavy-duty coil-on-plug assemblies engineered with high-conductivity internal copper windings and reinforced dielectric housings that resist thermal breakdown. Paired with six fine-wire iridium spark plugs, the set reduces required arc voltage, maximizes spark kernel propagation, and maintains exact electrode gap integrity under high combustion chamber pressures to restore smooth idle and responsive throttle delivery.
