Default Problem on intake manifold

Hello a friend on mine have a H3 2006 3.7l with a pipe on the manifold connected to .............. Nothing




I search everywhere and the only thing I found is this picture
Any idea about this factory modification ?
For the moment I close the pipe and no problems





Thanks a lot
