Ignition Coil and Iridium Spark Plugs for Mercedes Benz E-Class (2007-2009) 3.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2007-2009 Mercedes Benz E-Class

Primary Function: Restores factory ignition performance and eliminates high-rpm cylinder misfires by replacing degraded coil packs and worn spark plugs across all six cylinders.

The Stock E-Class Ignition Breakdown

The M272 3.0L V6 engine generates significant thermal loads within the tight confines of the W211 engine bay. Over time, prolonged heat soak causes micro-fractures in the factory epoxy resin and internal copper windings of the coil-on-plug packs. Combined with electrode erosion on aged spark plugs, this leads to secondary voltage leakage, erratic idle, loss of throttle response, and intermittent P0300-P0306 misfire trouble codes under load.

The Engineering Solution

This complete 6-cylinder ignition service kit features coil-on-plug units engineered with premium internal copper windings, reinforced dielectric housings, and factory-matched blade terminals for stable high-voltage output across the entire RPM range. Paired with high-melting-point fine-wire iridium spark plugs, the kit ensures low electrical resistance, stable combustion flame-front propagation, and resistance to thermal degradation.
