I prefer the generic flexible hose that I have in the photo. It's much more flexible than the OEM type which makes it easier to route and get connected. I do not recall what diameter it is supposed to be, but that one size fit both the round port on the air box, round connection at one defrost vent and the rather obround connection at the other defrost vent. This stuff is also good for pushing it out of the way if you have to "get up in there" with your hand to do some wiring, etc.

I got my glove box liner for my truck from GMC Pauls and it was as good as they get for being a stapled fiber-board liner.
