Ignition Coil and Iridium Spark Plugs for Mercedes Benz M-Class (2006-2011) 3.5L

High-Output Direct-Fit Ignition Kit for 2006-2011 Mercedes Benz M-Class

Primary Function: Restores factory spark output and combustion efficiency across all six cylinders to eliminate misfires, rough idle, and sluggish throttle response.

The Stock M-Class Ignition Degradation

Under-hood thermal cycling in the W164 chassis accelerates dielectric breakdown within the factory ignition coil epoxy potting and primary windings. Over time, heat soak and high electrical resistance cause internal micro-arcing, secondary winding failure, and premature plug erosion. This degradation leads to intermittent cylinder misfires (DTC P0300–P0306), unburned hydrocarbon loading on the catalytic converters, and sluggish power delivery under load.

The Engineering Solution

This complete 6-cylinder refresh kit features reinforced coil-on-plug assemblies engineered with high-purity copper windings, high-dielectric epoxy casing, and corrosion-resistant blade terminals for maximum conductivity. Paired with fine-wire iridium spark plugs, the system provides high thermal stability, consistent spark discharge across the entire RPM band, and rapid flame-kernel propagation to ensure complete combustion without triggering check engine lights.
