Hello folks. I'm looking to purchase some spark plugs and fuel filter for my '94 600SEL as part of the maintenance tune up that I'm planning to do but I need help choosing which one will work for my car:





Thanks in advance.

For the fuel filter, just look at what is on your car now, hose nipple connections or threaded connections, and buy the same filter. For spark plugs, there is nothing wrong with good ol' copper cores, F8DC4. Check your owner's manual. It will give you the recommended spark plug.

Checked the fuel filter this morning and it looks like my model has the threaded fittings.

Also, upon further research, the M120 owners in the R129 section recommend the F8DC4 plugs so I'll be getting those as well as a new spark plug wire set (my wires looked stripped and I'd rather not risk burning down the engine bay)

Thanks again everyone.
