What's this hose coming off the air cleaner box?
Fiddled around with my FD today and noticed a loose pipe coming off the airfilter box

It's a rubber 90 degree elbow with a plastic piece attached to it, the rubber attaches to a nipple on the right side of the airbox and the plastic piece is just hanging near the intercooler.
Looking to the nipple on the airbox some sort of mesh is visible

On the inside of the airbox is a box-shape

It's probably nothing important and not the reason why my car is running crappy, but the end of the plastic pipe looks like it should connect to something, which it doesn't and I can't find anything that it might fit on.

The returned unused air from the air pump comes back into the air box through that small internal muffler and out that side vent through that hose to atmosphere. It prevents the moo-fart noise.
