Difference between M102 2.0 and 2.3 engines?
 

Hi guys.. I've got a Euro 2.0 5-speed 190E. I know that there was the 1.8, 2.0, 2.3 and 2.6 that came factory stock from Mercedes. The 2.3-16 and 2.5-16 are "special" cars, so I will leave these out for now.

Am I correct to say that maintenance parts are exactly the same between a 1.8/2.0/2.3 M102? The 2.6 is a M103, so I would assume it would be different since it has 6 cylinders. But what about the 4 cylinder 8 valve motors? Are spark plugs, wires, rotors, distributor caps, etc the same? What about Euro 2.0 and US 2.3?

thanks
