Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2005-2006 Mazda Tribute

What it Does: Restores factory secondary ignition voltage and resolves cylinder misfires across the engine load range for the 2.3L Tribute platform.

The Stock Tribute Ignition Breakdown

The 2.3L MZR engine subjects factory coil-on-plug assemblies to continuous underhood thermal cycling. Over time, heat soak degrades the internal epoxy resin and insulation around the primary and secondary copper windings, causing dielectric breakdown. This insulation failure leads to secondary voltage leakage, intermittent spark dropouts, erratic idle, reduced combustion efficiency, and P0300–P0304 misfire fault codes under load.

The Engineering Solution

This direct-replacement ignition service pack utilizes high-grade internal copper windings sealed in premium thermal-resistant epoxy to resist internal voltage tracking and heat degradation. Paired with fine-wire iridium spark plugs, the package requires lower firing voltage while maintaining consistent spark kernel propagation across all engine speeds. Direct-fit blade terminals and factory-matched electrical connectors ensure plug-and-play installation without wire harness modifications.
