Basically its ODB1 versus ODB2.. The odb1 is aluminum (I believe) and the ODB2 is plastic. They are interchangeable, but, the hose that connects to the ICV is not the same. And you will have to do some modifications to make it fit. There is no benefit going to the ODB2 valve cover at all. I actually have the ODB1 cover on my S52 engine.
