I just pulled the plugs on my 95 E320 and found the plugs are Bosch Super RO 768. The manual calls for Bosch F 9 DCO. Do I have the right plugs, or are they only a reasonable facsimile? I bought the car used this past summer.

The RO # is a production code on the insulator.
The type # is stamped on the side of the metal base hex...

R Means resister....

Happy Motoring

I have found resistor plugs to be problematic. Get the F8DC4s like MB DOC recommends. The plug wires have resistor ends on them. Too much resistance, too much heat. Trouble lurks with the wrong plugs.

Found it! - F 8 DC4 stamped on the metal base. Thanks everybody.
