Ignition Coil and Iridium Spark Plugs for Chrysler Intrepid (1998-2004) 3.5L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 1998-2004 Chrysler Intrepid

What it Does: The Ignition Coil and Iridium Spark Plug Kit restores secondary ignition efficiency to the 1998-2004 Chrysler Intrepid 3.5L to eliminate engine misfires, stabilize idle, and maximize combustion pressure under load.

The Stock Chrysler Intrepid Secondary Ignition Failure

In the longitudinal LH chassis configuration, cylinder head packaging subjects coil-on-plug boots and pencil coil bodies to persistent engine bay heat soak. Over time, the factory coil insulation undergoes dielectric breakdown, allowing high-voltage secondary arc-through directly to the cylinder head walls. Concurrently, factory spark plug gap enlargement accelerates coil saturation fatigue, causing high-load misfire codes (P0300-P0306), sluggish transient response, unburned hydrocarbon emissions, and premature catalytic converter degradation.

The Engineering Solution

This complete tune-up kit replaces deteriorating factory components with reinforced pencil ignition coils and fine-wire iridium spark plugs. The coils utilize high-grade magnetic copper primary and secondary windings encased in a vacuum-poured dielectric epoxy to prevent internal insulation breakdown and flashover. Paired with laser-welded iridium electrode spark plugs, the package delivers a high-energy spark kernel with significantly reduced required firing voltage. High-temperature silicone boots seal out moisture and oil ingress in the plug wells, ensuring consistent spark delivery and optimal flame-front propagation across the combustion chamber.
