Ignition Coil and Iridium Spark Plugs for Dodge Durango (2000-2008) 4.7L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2000-2008 Dodge Durango

What it Does: Restores factory ignition energy and combustion stability across all eight cylinders on the 4.7L V8 platform.

The Stock Durango Ignition Breakdown

Over extended thermal cycling, factory coil-on-plug assemblies on the 4.7L PowerTech V8 suffer from dielectric insulation degradation and micro-cracking within the internal copper windings. Paired with standard spark plug electrode erosion, this voltage leakage leads to severe spark drop-out under load, rough idling, hesitation while towing, and common P0300-P0308 cylinder misfire codes.

The Engineering Solution

This complete 8-cylinder ignition overhaul kit pairs eight high-output coil packs with fine-wire iridium spark plugs. The coils feature premium high-conductivity copper windings insulated with high-dielectric epoxy potting to withstand underhood heat soak. The laser-welded iridium electrode spark plugs resist arc erosion, lowering firing voltage demand and ensuring complete flame propagation during heavy engine loads.
