Looks like ducting for venting for a vehicle like a heavy duty truck or something.
Yeah, I was thinking "if" auto ducting it would be under dash ducting as opposed to engine compartment.

Could be either. I have seen some large ducting on older tandem trucks that's exposed right under the dash board that looks similar.
I'm inclined to think automotive applications, simply by the apparent small gauge of the reinforcing wire; not aircraft or similar grade application by any means due to that itself...
This is a pic of some AC hose from a 1964 Valiant...
Keep in mind, the wire support may have absolutely nothing to do with the amount of air pressure going thru the hose, but may be there to keep the hose from collapsing due to sharp bends to fit from one place to another...
This particular hose seems to have a small gauge spiral wire, as opposed to the larger diameter wires that we're seeing in previous pics...
If someone ID's the correct hose and the available source, PM me and as a reward I'lll GIVE them a tie pilot helmet.
Can't see enough to tell anything.
I'd be interested in seeing the AT-AT hose as well!
Trying to figure this out for a long time myself. I still think it's a car hose after looking through hose after hose for several years.
