The turbo kit I got for my Focus came with a Blitz DD BOV which I will not be using so it is for sale. I has never seen boost and comes with everything that Blitz sent with it; gasket, flange, vacuum hose, clamps, T-valve. Would like to get at least $75 for it. Will have to remove the flange from my charge piping. Don't have pics yet, but this is a pic of what it looks like:
