Ignition Coil & Iridium Spark Plugs for Mercedes-Benz C230 (2006-2009) 2.5L V6

High-Output Ignition Coil & Iridium Spark Plug Kit for 2006-2009 Mercedes Benz C-Class

What it Does: This direct-replacement ignition coil and iridium spark plug set resolves misfires and restores factory combustion efficiency for the 2.5L M272 V6 engine.

The Stock C-Class Ignition Weakness

The factory ignition coils on the Mercedes-Benz M272 2.5L V6 are highly susceptible to thermal degradation. Positioned directly atop the valve covers, the OEM coils endure extreme engine bay heat cycling. Over thousands of miles, the factory epoxy degrades, leading to micro-cracks in the coil housing. This allows voltage to arc to the cylinder head rather than jumping the spark plug gap, manifesting as a rough idle, hesitation under load, and persistent P0300-series misfire codes. Additionally, standard factory spark plugs experience electrode wear that widens the gap, increasing electrical resistance and accelerating premature coil failure.

The Engineering Solution

This comprehensive ignition kit engineered for the W203 and W204 chassis rectifies these inherent thermal vulnerabilities. Each coil features an upgraded internal primary and secondary winding utilizing high-purity copper wire to maximize voltage output while maintaining lower internal operating temperatures. The outer housings are molded from a high-dielectric polymer to resist thermal cracking and prevent voltage leaks. Paired with this coil set are six iridium-tipped spark plugs. The ultra-fine iridium center electrode significantly reduces the voltage required to bridge the spark gap, decreasing the load on the ignition coils. This results in a cleaner, more complete fuel burn, providing enhanced spark energy, restoring lost throttle response, and stabilizing idle characteristics.
