Ignition Coil and Iridium Spark Plugs for Mercedes Benz E-Class (1998-2005) 3.2L

Direct-Fit Ignition Overhaul Kit for 1998-2005 Mercedes Benz E-Class

What it Does: Restores factory combustion efficiency and stabilizes multi-spark timing across all cylinders for the twin-spark M112 V6 powertrain.

The Stock E-Class Ignition Breakdown

The Mercedes-Benz M112 twin-spark ignition system utilizes two spark plugs per cylinder driven by a dual-output coil pack. Over thermal cycles, engine bay heat soak degrades the factory primary and secondary coil windings, leading to internal dielectric breakdown, micro-arcing, and intermittent cylinder misfires (P0300-P0306). Simultaneously, degraded standard copper or platinum plugs suffer gap erosion, increasing secondary voltage demand and causing premature coil failure, rough idle, and decreased fuel efficiency.

The Engineering Solution

This complete service kit features six high-grade ignition coils engineered with high-conductivity internal copper windings and reinforced thermoplastic housings to withstand extended thermal loads. Paired with twelve fine-wire iridium spark plugs, the assembly lowers the required firing voltage while providing a focused, high-intensity spark kernel. Blade terminals and OEM-geometry connectors ensure stable resistance and direct plug-and-play installation without wire harness modification.
