Ignition Coil and Iridium Spark Plugs for Mercedes Benz GLK-Class (2010-2012) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2010-2012 Mercedes Benz GLK-Class

Complete Ignition Overhaul: Restores factory combustion efficiency, eliminates cylinder misfires, and stabilizes idle by replacing heat-stressed coil packs and eroded plugs with precision-matched ignition components.

The Stock GLK-Class Ignition Breakdown

Under prolonged engine bay thermal cycling, the factory coil packs on the Mercedes-Benz M272 3.5L V6 suffer from dielectric breakdown in the epoxy housing and thermal degradation of the primary and secondary copper windings. This leads to secondary voltage leakage, intermittent hesitation, rough idle, and cylinder-specific misfires (DTCs P0300-P0306). Simultaneously, OEM plug gap erosion increases electrical resistance, forcing the ignition system to operate near its thermal limits and accelerating coil failure.

The Engineering Solution

This comprehensive service pack combines heavy-duty coil-on-plug assemblies with high-ignitability fine-wire iridium spark plugs. The coils feature reinforced internal copper windings and high-dielectric silicone boots that insulate against high-voltage arc-over, thermal stress, and oil contamination. The fine-wire iridium plugs reduce ignition voltage requirements, ensuring rapid flame propagation and reliable combustion across all load conditions while matching OEM electrical resistance specifications.
