Ignition Coil + Spark Plugs and Wires for Mercedes Benz C-Class (1998-2000) 2.8L

Direct-Replacement Ignition Overhaul Kit for 1998-2000 Mercedes Benz C-Class

What it Does: The Ignition Coil, Spark Plug, and Wire Kit replaces degraded factory ignition components on the 1998-2000 Mercedes Benz C-Class to eliminate cylinder misfires, stabilize idle quality, and restore peak combustion efficiency.

The Stock Mercedes Benz C-Class Ignition Breakdown

The M112 2.8L V6 in the W202 chassis relies on a dual-spark per cylinder configuration (two plugs and paired secondary leads per cylinder). Due to sustained under-hood thermal cycling, the factory epoxy casings on the primary coils micro-crack over time. This breakdown causes dielectric failure, voltage leakage to the cylinder heads, and high-rpm misfires. Simultaneously, carbon fouling and worn electrode gaps on the twelve twin-spark plugs strain the aging secondary ignition wires, leading to elevated primary resistance, unburned hydrocarbon buildup, catalytic converter degradation, and recurring P0300 through P0306 DTC faults.

The Engineering Solution

This comprehensive ignition service kit addresses high-resistance voltage drop across all six combustion chambers. Each ignition coil features high-dielectric epoxy housing and optimized copper primary/secondary windings to prevent thermal arc-through under load. The included twelve matched spark plugs maintain precise electrode gaps for uniform flame-front propagation, while the silicone-jacketed spark plug wire set resists heat soak, oil contamination, and radio frequency interference (RFI). Replacing coils, leads, and plugs simultaneously balances coil saturation time and delivers consistent secondary kilovolt output across the entire rev range.

Frequently Asked Questions

Does this fit the W202 C-Class?
Yes, this is a direct fit for the 1998-2000 Mercedes Benz C-Class equipped with the M112 2.8L twin-spark V6 engine.

Do I need to apply dielectric grease to the spark plug boots during installation?
Yes, applying a thin coat of dielectric grease inside the wire boots prevents moisture ingress and eliminates high-voltage arcing to the plug insulator.
