New to LS1 question

Ok, just got mine , anyway, it has an aftermarket airbox (MTI) and next to it sits the end of a hose w/ a breather on it, and it goes down to something in the bumper, not sure what this is? Also do I just leave the breather there or what? It doesn't look so good so i want to do something with it.

not sure exactly, maybe an airtemp sensor

It's pretty big, so i don't know

It should be the normal of size a valve cover breather would be..Likely a K&N or a copy.. if not get a K&N and 1.Cut tip of the hose.. appyly a screwset tighning device(from you local hardware)
2. For connection of the hose to the breather element tighten screw clockwise..
3. Secure to ABS stalk on the (right-facing)side

Oh, i mean the object hidden in the front bumper is kinda big, the hose from the breather runs into this "box" and then another hose exits and comes back out
