Ok I just installed a forge rs bov and since it fits into the stock location it wasnt hard at all to install. My big question is while doing that I was looking at the hose coming off the turbo directly under the bov, there is a nipple about an inch or so long and it was uncapped.My question is what is it for one and should it be connected to something. Its all stock hoses and piping.

 

i can get a pic if anyone needs one
