Ignition Coil and Iridium Spark Plugs for Chrysler Concorde (1998-2004) 2.7L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 1998-2004 Chrysler Concorde

What it Does: Restores factory secondary ignition voltage, resolves under-load misfire codes, and stabilizes idle combustion across the entire rev range.

The Stock Concorde Ignition Degradation

On the Chrysler LH platform, the deep-well spark plug configuration in the DOHC 2.7L cylinder head subjects factory coil-on-plug assemblies to intense thermal cycling. Over extended mileage, radiant head heat breaks down internal coil epoxy insulation and degrades copper winding continuity. This insulation breakdown results in dielectric punch-through, spark arc-over, carbon tracking on the boots, and incomplete combustion that triggers diagnostic trouble codes (DTC P0300-P0306).

The Engineering Solution

This complete 6-cylinder ignition service kit replaces tired factory components with vacuum-potted, high-conductivity copper coil windings and durable direct-fit blade terminal connectors. Paired with fine-wire iridium spark plugs, the assembly lowers the required firing voltage, accelerates flame front propagation, and provides consistent high-kV output to prevent spark blowout under aggressive throttle application.
