Please use this for reference only since I have a 1996 C 220.
On the top center of the motor is a cover over the spark plugs. Remove the cover and you should see your plug wires. Obviously just unplug wires and remove the plugs. However I did not have a spark plug wrench the held the plug so I had to put the plug into the wire and slightly twist the plug into the opening. I then removed the wire again and used the wrench to tighten. Only do one plug at a time obviously.
