Ignition Coil and Iridium Spark Plugs for Chrysler Concorde (2002-2004) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2002-2004 Chrysler Concorde

What it Does: Replaces degraded factory coil-on-plug packs and worn plugs to restore precise secondary ignition voltage, eliminate misfires, and stabilize idle.

The Stock Concorde Ignition Breakdown

The Chrysler LH-platform 3.5L V6 operates in tight engine bay packaging that traps excessive thermal energy around the cylinder heads. Over time, heat cycles degrade the stock coil insulation and copper windings, causing dielectric breakdown, micro-arcing, and intermittent under-load misfires. Simultaneously, standard copper or platinum core spark plugs suffer from rapid electrode erosion, widening the spark gap, overworking the secondary ignition coils, and causing rough idle and poor fuel economy.

The Engineering Solution

This direct-replacement service kit pairs high-grade replacement coil-on-plug units featuring high-conductivity internal copper windings with fine-wire iridium spark plugs. The reinforced epoxy coil casing resists thermal fatigue and dielectric leakage, maintaining uniform high-voltage spark delivery. The iridium center electrodes provide superior wear resistance against spark erosion, allowing a consistent gap, lower voltage demand on the primary ignition circuit, and cleaner flame-front propagation across all cylinders.
