Ignition Coil and Iridium Spark Plugs for Plymouth Prowler (1999-2001) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 1999-2001 Plymouth Prowler

Complete Ignition Tune-Up Solution: Restores factory secondary ignition voltage and resolves cylinder misfires, rough idling, and hesitation on the high-output 3.5L V6 engine.

The Stock Prowler Ignition Coil Degradation

Due to the compact engine bay of the aluminum PR platform, the high-output 3.5L EGG V6 operates under sustained thermal stress. Over time, heat soak compromises the factory coil-on-plug epoxy insulation and degrades the internal copper windings, resulting in micro-arcing and secondary voltage drop. Combined with eroded spark plug gaps over high mileage, weak spark delivery leads to unburnt hydrocarbon buildup, sluggish throttle response, and intermittent misfire trouble codes (P0300-P0306).

The Engineering Solution

This direct-replacement kit provides six heavy-duty ignition coil packs manufactured with premium internal copper windings, reinforced thermoplastic housings, and heat-resistant silicone boots to eliminate dielectric breakdown. Paired with six fine-wire iridium spark plugs, the assembly guarantees rapid flame kernel propagation, consistent high-voltage transfer across all RPM ranges, and optimized combustion efficiency under load.
