While doing my regular maintenance, I noticed there was a loose hose coming from the airbox right after the MAF. I can't seem to find where it's attached to? Any suggestions? Thanks

Is it coming from the transmission?

Looks a little long to be the transmission breather hose, but might be.
If so it just vents to atmosphere.

One end is attached to airbox right after the MAF, the loose end I can't seem to find where to connect it to.

This is a gen 5? 3.0L motor?




I think it's a transmission breather hose? Check MT-13. The transmission is underneath by the driver side area where the airbox is and your other cables are connected.
