I have always had my 1991 300SE professionally maintained, but now that I am retired and have more time and less money, I would like to start doing some of the routine maintenance myself. It needs new plugs, so I thought that would be a good start (I used to tune up my American cars when I was young and never had any problems, but that was back in the carburetor and points days).
I assume that it has Bosch plugs in it - should I continue to use them? Can anyone tell me the plug number and gap and torque specifications for this engine? Any special tools or procedures required?
Thanks,
Jim Norfolk
