So now I have my stock cdv with the internals knocked out if anyone wants it. Looking at the hole it seems to be exact same size as the one I got from mattv. No drilling was done so I doubt there are any structural issue with the valve.
does it make much of a difference? can you feel it? did it cost you much to have the cdv valve replaced?
