Ignition Coil + Spark Plugs for Mercedes Benz C-Class (1997) 3.6L

High-Output Ignition Coil and Spark Plug Kit for Mercedes Benz C-Class (W202)

What it Does: The Ignition Coil and Spark Plug Kit restores primary and secondary ignition efficiency on the Mercedes Benz C-Class to eliminate high-load misfires and stabilize combustion across all cylinders.

The Stock Mercedes Benz C-Class Thermal Breakdown

On the W202 chassis powered by the hand-assembled M104.941 3.6L inline-six, thermal saturation beneath the top cylinder head cover rapidly degrades factory ignition coils. Operating on a waste-spark setup, each coil fires twice per cycle—doubling the electrical and thermal duty cycle compared to conventional sequential setups. Over decades of heat soak, factory epoxy insulation suffers dielectric breakdown, leading to carbon tracking, erratic dwell timing, spark blowout under load, and persistent P0300–P0306 misfire codes.

The Engineering Solution

This comprehensive refresh kit provides three precision-wound ignition coils alongside six matched spark plugs to restore factory energy transfer. The replacement coils feature vacuum-potted epoxy insulation and high-conductivity copper primary and secondary windings engineered to resist thermal degradation and internal shorting. Combined with spark plugs tailored to factory heat-range and resistance specifications, this direct-replacement assembly provides steady secondary voltage, ensuring crisp throttle response, clean combustion chamber burn, and smooth idle across all companion cylinders.

Frequently Asked Questions

Does this fit the W202 C-Class?

Yes, this is a direct fit for the 1997 Mercedes Benz C-Class equipped with the M104.941 3.6L engine.

Why does the kit include three ignition coils for a six-cylinder engine?

The 3.6L inline-six utilizes a waste-spark ignition configuration where three dual-tower coils each fire two synchronized cylinders simultaneously.

The Mercedes Benz Precision Standard

Manufactured to strict European engineering tolerances, this direct-fit ignition kit ensures uncompromised combustion synchronization without triggering check engine lights or requiring ECU recalibration.
