1998 V6 - What is this line called?

[98_Stanger]

This line runs from the driver side I guess header cover to my cold air intake. Can anyone help me figure out what line this is. Also, the AC doesn’t blow through the vents, but the blower works. The resistor works, and the line is rigged together to stay connected. Just wanted to know if anyone knew how to fix this issue because it’s really hot in Texas. I recently purchased a kind of beat up 98 Ford Mustang V6 and wanted to get it back to its former glory. Only bad thing is I don’t know much about cars and this is my first real project car so I’m replacing what I can so that the car will run smoothly as it should.

Looks like either a high or low pressure line.

Any idea what it does

Oh sorry I briefly looked at the photo without actually opening it and you were talking about the AC system so I figured it was a high/low pressure line. bUT, since it’s plugged into your CAI, it’s definitely not what I was thinking. I wonder if it’s your ACT sensor.

I’m not as familiar with newer mustangs and especially v6’s but I know they moved the ACT to the intake in later years.

Where does that line go to on the drivers side of the car. It disappears behind the intake but then I can’t see where it goes.

That line looks like rocky raccoon rigged it up.
I have no eye deer what its called but it reminds me of the line on my 5.0, comes from the oil fill and goes to the tb.
