Ignition Coil + Spark Plugs for Mercedes Benz S-Class (2000-2006) 5.0L

Direct-Replacement Ignition Coil and Spark Plug Kit for 2000-2006 Mercedes Benz S-Class

What it Does: The ignition coil and spark plug kit restores factory combustion efficiency and eliminates cylinder misfires on the 2000-2006 S-Class by delivering precise, high-dielectric secondary voltage to the twin-spark ignition system.

The Stock Mercedes Benz S-Class Coil Breakdown and Heat Soak

The factory twin-spark ignition system on the W220 chassis relies on a dual-lead coil for each cylinder to ignite two independent spark plugs. Over extended heat cycles, the factory coil casing and internal epoxy resin suffer thermal degradation, developing micro-fractures in the secondary winding insulation. Combined with electrode wear that widens spark gaps over mileage, the engine management system must step up secondary voltage to bridge the gap. This elevated electrical resistance leads to punch-through dielectric breakdown, severe carbon tracking on the coil towers, intermittent misfires under load (P0300–P0308 DTCs), rough engine idle, and unburned fuel wash into downstream catalytic converters.

The Engineering Solution

This comprehensive ignition service kit supplies eight direct-fit coil packs and sixteen matched spark plugs tailored specifically to the twin-spark M113 V8 platform. Coils are built with vacuum-potted epoxy insulation and high-grade copper windings engineered to resist thermal degradation and internal shorting under harsh under-hood temperatures. Paired with corrosion-resistant, factory-gapped spark plugs featuring robust copper cores and nickel-alloy ground electrodes, this combination ensures uniform flame propagation, minimal electrical impedance, and stabilized dwell time across all combustion chambers. Replacing both coils and plugs simultaneously eliminates secondary voltage drops, instantly clearing ignition-related driveability faults.
