What is this ?

This is attached to the throttle body.
My S&B air intake was rubbing on this line may need some fixing.

You’re looking at one of the vacuum/emissions lines for the truck’s EVAP or PCV system, and it feeds straight into the front of the supercharger. The silver piece on the right is the actuator for the supercharger bypass valve, and the black housing on the left is the throttle body.

Because the Ram TRX needs a huge amount of airflow, aftermarket intakes like the S&B use a very large intake tube. Space gets tight, and that tube coming from the passenger‑side airbox can end up resting on, or sagging against, this hard plastic emissions line.

The reason this becomes a problem is simple: if the engine moves around and the intake tube rubs through that plastic line or the 90‑degree elbow, you’ll get unmetered air entering the supercharger. That creates a vacuum leak. When that happens, the truck can start idling rough, lose performance, and eventually trigger a Check Engine Light with lean or EVAP‑related codes.

In short, if that line gets damaged, the truck won’t run right, so it’s worth fixing before it becomes an issue.

Appreciate the response man, might switch to a Bwoody at this point.
