1999.5 jetta aftermarket intake help

hey guys.. just installed a ghetto aftermarket intake in my 2.0 jetta.. (anything is better than the stock air box).. anyway, i took out the stock box, and fit the intake pipe on.. afterwards, i tightened up all the fixtures, and remembered i disconnected a hose that was attached to the stock air box.. after i was done with installing the intake, i noticed it was still hangin there.. what do i do with it.. it seems to be the air pump hose?.. do i attach a filter to it?.. someone help.. lol

Yes, you want to attach a filter to it or you will be injecting dirty air into your 2ndary air pump. just put on a crankcase breather filter on the end. Or take the pipe off the pump and put the filter directly on the pump (with hose clamps of course)
