What does this hose attach to?

When changing out cooling systems hoses and throttle body, I came across a hose that I don't know what it connects to. I do have a supercharger so I don't know if that has something to do with it. Any ideas? Attached a youtube vid

i had the same issue when replacing my ccv, it gave me a misfire, there is a connection underneath the intake manifold that this plugs into.

100%, it wraps around the underside of the intake... I've definitely knocked that off before, not a fun fix lol.

Any good tricks for re-attachment?

Turns out it was a diff. hose (having to do with supercharger setup) that got loose, and it was not hard to reattach. Phew! [emoji3]

It was the fuel breather vent hose. Luckily on JR's car, we were able to reach it sitting behind the ICV
