Ignition Coil + Spark Plugs for Mercedes Benz CL-Class (2007-2010) 5.5L

Direct-Fit Ignition Coil and Spark Plug Kit for 2007-2010 Mercedes Benz CL-Class 5.5L (C216 / M273)

What it Does: The Direct-Fit Ignition Coil and Spark Plug Kit replaces degraded ignition components on the 2007-2010 CL-Class to eliminate cylinder misfires, restore lost combustion efficiency, and stabilize idle operation.

The Stock Mercedes Benz CL-Class Ignition Breakdown

The naturally aspirated 5.5L M273 V8 in the C216 chassis generates significant thermal mass in an enclosed engine bay. Over continuous heat-soak cycles, the factory ignition coil epoxy potting and dielectric rubber boots harden, crack, and micro-arc against the cylinder head bores. This internal voltage dissipation causes secondary ignition collapse, fouled spark plugs, sluggish throttle response, and persistent misfire trouble codes (P0300–P0308) under heavy open-throttle load.

The Engineering Solution

This comprehensive tune-up kit restores factory-rated spark energy using eight matched coil-on-plug units and eight NGK G-Power platinum-tipped spark plugs. The ignition coils feature high-permeability magnetic silicon steel cores and high-grade copper windings insulated with premium epoxy resin to withstand extreme engine bay heat without dielectric breakdown. Paired with fine-wire platinum center electrodes, this set ensures a stable arc, uniform flame front propagation, and rapid throttle response while directly superseding OEM part numbers 0001501980, 0001502680, and 2729060060.

Frequently Asked Questions

Does this fit the C216 CL-Class?
Yes, this is a direct fit for the 2007-2010 Mercedes Benz CL-Class equipped with the M273 engine.

Do these spark plugs require pre-gapping before installation?
These NGK spark plugs arrive pre-gapped, though verifying the factory 0.031-inch gap before final torque installation is recommended service practice.

The Mercedes Benz Precision Standard

Calibrated specifically for European electronic engine management, these matched ignition components maintain exact primary and secondary resistance values to guarantee smooth power delivery without triggering false CEL misfire codes.
