Ignition Coil and Iridium Spark Plugs for Mercedes Benz C-Class (2006-2011) 2.5L

Direct-Replacement High-Dielectric Ignition Kit for 2006-2011 Mercedes Benz C-Class

What it Does: Restores precise ignition timing and spark energy across all six cylinders to eliminate misfires, stabilize rough idle, and recover factory throttle response.

The Stock C-Class Ignition Coil Degradation

Under continuous operating conditions, the M272 engine bay subjects factory ignition coils to severe thermal cycling. Over time, heat soak degrades the internal epoxy encapsulation and breaks down the insulation around the secondary copper windings. This leads to dielectric failure, micro-arcing, high-load misfires (OBD-II codes P0300 through P0306), unburned fuel accumulation, and reduced fuel economy.

The Engineering Solution

This complete ignition kit features six high-output coil-on-plug units engineered with premium copper windings and durable thermoplastic housings to resist thermal fatigue. Paired with six fine-wire iridium spark plugs, the assembly minimizes quenching, lowers required firing voltage, and provides a stable, concentrated spark kernel for efficient, complete combustion under demanding driving conditions.
