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

Direct-Fit Ignition Coil and NGK Iridium Spark Plug Kit for 2000-2006 Mercedes Benz CL-Class (C215)

What it Does: The Ignition Coil and Iridium Spark Plug Kit restores factory combustion efficiency and stabilizes idle on the 2000-2006 CL-Class by delivering high-dielectric secondary voltage across all 16 combustion points.

The Stock Mercedes Benz CL-Class Secondary Ignition Degradation

The twin-spark M113 V8 relies on dual spark plugs per cylinder fired sequentially to achieve complete flame front propagation and low emissions. Over thermal cycles within the tightly packaged C215 engine bay, factory coil packs suffer internal epoxy insulation breakdown and primary-to-secondary winding short circuits. Combined with widening electrode gaps on worn standard plugs, resistance climbs dramatically. This thermal fatigue leads to intermittent secondary breakdown under load, rough idle, unburned hydrocarbon buildup, and recurring P0300-P0308 multi-cylinder misfire codes that trigger limp mode.

The Engineering Solution

This service kit replaces all failure-prone ignition components with eight high-output dual-tower coil packs and sixteen pre-gapped NGK Iridium IX (BKR5EIX-11) plugs. The coils feature reinforced PBT housings and high-temperature vacuum-poured epoxy to prevent dielectric punch-through under high under-hood heat soak. Paired with ultra-fine 0.6mm laser-welded iridium center electrodes, this configuration requires lower ionization voltage, promotes immediate quenching resistance, and maintains razor-sharp flame kernel development across the twin-plug combustion chamber.

Frequently Asked Questions

Does this fit the C215 CL-Class?

Yes, this is a direct fit for the 2000-2006 Mercedes Benz CL-Class equipped with the M113 5.0L twin-spark engine.

Are spark plug wires included in this service pack?

No, this kit supplies the 8 dual-lead coils and 16 NGK iridium spark plugs; reusable factory secondary leads or new direct-fit wire sets must be utilized.
