stock air box mistery

[brundish24]

hi as i was takeing off the air box the first thing i noticed was a hose/pipe coming out of the air box and was not connected to anything just wondering is this normal here is a pic of the pipe its comes from the right side of the air box and then goes down to what i think is the radiator and i cant find any thing to connect it to, the pipe it self is part hose at the top and hard plastic
does anyone have a clue.

Thats normal.  It doesnt connect to anything, it just hangs off the airbox.
