• Loss of throttle response from aged plugs

Installation Notes and Tips

Verify the engine application against the fitment list before installation. Check the plug gap against the vehicle service specification, even though this plug is pre-gapped at 1.1 mm. Use the correct torque procedure for the cylinder head material and confirm the flat seat style matches the original equipment design. Some Mercedes-Benz applications in the fitment data note that two spark plugs are required per cylinder; follow the vehicle service information for the exact engine configuration.
