Ignition Coil and Iridium Spark Plugs for Chrysler Pacifica (2007-2008) 4.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2007-2008 Chrysler Pacifica

What it Does: Restores factory secondary ignition output and precise flame propagation by replacing fatigued coil-on-plug assemblies and eroded spark plugs on the 4.0L V6.

The Stock Pacifica Secondary Ignition Degradation

The transversal layout of the 4.0L SOHC V6 in the CS chassis subjects rear bank coil boots and internal secondary windings to continuous thermal saturation. Over time, OEM primary winding epoxy breaks down, inducing dielectric breakdown, micro-arcing, and intermittent misfires under heavy load or throttle tip-in. Concurrently, factory standard nickel-copper plugs suffer severe electrode gap erosion, increasing secondary voltage demand past the output threshold of aged coil windings.

The Engineering Solution

This comprehensive ignition service kit supplies six direct-fit coil-on-plug packs engineered with high-conductivity copper primary and secondary windings encased in premium epoxy to resist thermal degradation and voltage leak. Paired with fine-wire iridium-tipped spark plugs, this kit requires significantly lower ionization voltage while providing superior spark kernel stability, crisp throttle response, stable idle quality, and complete combustion across the RPM range.
