Ignition Coil and Iridium Spark Plugs for Mazda MPV (2002-2006) 3.0L

Direct-Fit Ignition Service Kit for 2002-2006 Mazda MPV

Primary Function: Restores secondary ignition voltage and combustion efficiency across all cylinders by replacing fatigued factory coil packs and eroded plugs.

The Stock MPV Ignition Degradation

On the transverse 3.0L V6 powerplant, the rear bank coil-on-plug assemblies endure constant heat soak trapped against the firewall. Over time, thermal cycling degrades the factory internal epoxy and secondary windings, causing dielectric breakdown, micro-arcing, rough idle, and typical P0300 through P0306 diagnostic misfire codes under load.

The Engineering Solution

This complete ignition overhaul kit includes 6 heavy-duty coil packs and 6 matching fine-wire iridium spark plugs. The coil assemblies are built with high-conductivity internal copper windings, reinforced thermoplastic housings, and heat-resistant silicone boots to isolate voltage leaks. Paired with high-melting-point iridium electrodes, this setup lowers ignition voltage demand, resists electrode erosion, and ensures clean, complete flame propagation under all driving conditions.
