Ignition Coil + Spark Plugs for Mercedes Benz C-Class (1994-1997) 2.8L

Direct-Fit Ignition Coil and Spark Plug Refresh Kit for 1994-1997 Mercedes Benz C-Class

What it Does: The complete ignition kit replaces aged ignition coils and worn plugs on the 1994-1997 C-Class to eliminate cylinder misfires, stabilize idle speed, and restore peak combustion efficiency.

The Stock Mercedes Benz C-Class Wasted-Spark Degradation

The M104 2.8L inline-six relies on a dual-fire wasted-spark layout where three primary coils mount directly over spark plugs 2, 4, and 6 while driving cylinders 1, 3, and 5 via secondary leads. Trapped under the cast aluminum valve cover cosmetic shield, these factory coils endure intense thermal cycling that breaks down internal epoxy insulation over time. This leads to secondary dielectric puncture, high-RPM spark blowout, rough warm idle, and unburned hydrocarbon wash that risks fouling the catalytic converter.

The Engineering Solution

This direct-replacement ignition package features high-dielectric epoxy housing and precision-wound copper windings designed to resist thermal breakdown and provide consistent dwell saturation under load. Paired with matched-gap spark plugs, this kit stabilizes spark discharge energy across all six cylinders. Restoring correct primary and secondary resistance preserves the factory EZL ignition control unit, sharpens throttle modulation, and eliminates hesitation under wide-open acceleration.
