I just installed a ABD Q-FLOW intake on my 01' GTI. While I was removing the airbox I notice that there were two hoses going to it. One was the MAS and the other was right beneath it that ran to the engine cover. The thing is, is that the little hose under the MAS isnt attatched to anything any more. Is that just a breather hose, and if so will it do any harm to leave it open and unattatched. One more thing, Does anyone know where to get a nice looking breather filter from. Thank for all you help.
