Ignition Coil + Spark Plugs for Mercedes Benz CL-Class S-Class (2001-2002) 5.5L

Direct-Fit OEM Replacement Ignition Coil and Spark Plug Kit for 2001-2002 Mercedes Benz CL-Class, S-Class (W220 / C215)

What it Does: The ignition coil and spark plug kit replaces aged factory secondary ignition components on the 2001-2002 Mercedes-Benz CL55 and S55 AMG to restore factory combustion efficiency, eliminate cylinder misfires, and stabilize idle quality.

The Stock Mercedes Benz CL-Class, S-Class Secondary Ignition Degradation

The naturally aspirated 5.4L M113.960 V8 utilizes a twin-spark ignition design requiring dual plug wires per cylinder powered by eight shared dual-tower coil packs. Due to extreme underhood thermal cycling trapped beneath factory engine covers, the original ignition coil secondary windings develop internal dielectric breakdown, while the epoxy casings micro-crack. This heat stress leads to unmetered voltage leakages, resistance drift across the secondary windings, and high-rpm spark blowout. Coupled with worn center electrodes on high-mileage spark plugs, the widened gaps force the coils to operate at elevated saturation levels, accelerating failure, triggering persistent P0300-P0308 DTCs, and degrading catalyst longevity.

The Engineering Solution

This comprehensive service kit renews the entire primary and secondary ignition loop by pairing eight direct-fit dual-output ignition coils with sixteen pre-gapped Denso PK16TT twin-tip platinum spark plugs. Engineered to match OEM 0001587803 impedance parameters, the replacement coils incorporate high-dielectric epoxy potting and premium magnetic core laminations to resist heat-induced thermal degradation. The included twin-tip spark plugs utilize a fine-wire 1.1mm platinum center electrode and titanium-enhanced ground electrode, minimizing quench effects and lowering the required ionization voltage. This matched set eliminates misfire conditions under heavy load and restores crisp throttle response.

Frequently Asked Questions

Does this fit the W220 / C215 CL-Class, S-Class?

Yes, this is a direct fit for the 2001-2002 Mercedes Benz CL-Class and S-Class equipped with the naturally aspirated M113 5.5L AMG engine.

Are plug wires included with this complete 16-plug ignition kit?

No, this service kit includes 8 dual-tower ignition coils and 16 Denso spark plugs; replacement high-voltage lead wires must be sourced separately if needed.

The Mercedes Benz Precision Standard

Maintaining the tight ignition tolerances of AMG-tuned Euro powerplants requires components that prevent DME trouble codes and maintain stoichiometric balance. This kit provides factory-level primary voltage stability and crisp flame propagation without throwing CEL errors or triggering limp-mode adaptations.
