Ignition Coil and Iridium Spark Plugs for Mercedes Benz C-Class (2006-2012) 3.0L

OEM-Grade Ignition Coil and Iridium Spark Plug Service Kit for 2006-2012 Mercedes Benz C-Class

Direct-fit ignition overhaul package: Replaces degraded factory coil packs and worn spark plugs to eliminate secondary ignition misfires, stabilize idle harmonics, and restore factory combustion efficiency on 3.0L V6 engines.

The Stock C-Class Ignition Breakdown

The factory ignition architecture on the naturally aspirated M272 3.0L V6 operates under severe thermal loads directly above the exhaust manifolds. Over extended heat cycling, OEM coil packs develop micro-fractures in their silicone boots and suffer dielectric breakdown within the internal epoxy potting. Coupled with high-mileage spark plug gap erosion, this generates increased secondary resistance, erratic dwell timing, rough idle, and unburned fuel delivery that triggers P0300 through P0306 DTC misfire codes.

The Engineering Solution

This comprehensive service kit upgrades your ignition system with six coil-on-plug assemblies manufactured with pure electrolytic copper primary and secondary windings and high-dielectric epoxy insulation to eliminate internal arc-over. Paired with six fine-wire laser-welded iridium electrode spark plugs, this kit provides superior ignitability, rapid flame kernel propagation, and extreme resistance to fouling. Direct-fit blade connectors ensure seamless communication with the factory Bosch ME9.7 ECU without signal drift.
