Ignition Coil and Iridium Spark Plugs for Dodge Intrepid (2000-2004) 3.5L

Direct-Fit Ignition Tune-Up Kit for 2000-2004 Dodge Intrepid

Complete Ignition Refresh: This 6-coil and 6-iridium-plug system replaces heat-stressed factory ignition components to restore full secondary voltage and stabilize combustion across all 6 cylinders.

The Stock Intrepid Thermal Breakdown

Underhood thermal cycling in the LH platform engine bay accelerates dielectric breakdown in the factory coil epoxy potting and degrades the silicone boots. This leads to high-voltage secondary arc leakage, carbon tracking, and intermittent misfires under load. Concurrently, standard electrode plugs suffer gap erosion, increasing overall circuit resistance and placing excessive thermal stress on the coil windings, resulting in hesitant acceleration, rough idle, and unburned hydrocarbon emissions.

The Engineering Solution

This service kit pairs high-dielectric UF269 coil-on-plug packs with wear-resistant fine-wire iridium spark plugs. Each coil assembly features high-purity internal copper windings sealed in high-grade epoxy to prevent internal shorting and thermal degradation. The fine-wire iridium center electrodes significantly reduce the required firing voltage, providing a hotter, more concentrated flame kernel that optimizes cylinder combustion and guarantees crisp throttle response across the power band.
