Hey, it works. It has been on there for 20K miles. Cable attaches to a manual pull cable to provide warm air when ambient temperature is cool or humid. See warm-air mod gallery.

Reason: More pictures.
This looks like a pretty interesting set-up. I like it, but can you get some wider angle shots on it and installed? I have 3-4 extra air cleaner assemblies I picked up and was thinking of doing a similar set-up and making one of them into a dual snorkel. The PO on mine had made a "cold-air" intake using a late 90's plastic intake with a not so amazing hole he cut in the radiator support. Yours is way more high-tech version. Nicely done.
Just inner-tube covered pipe strap, with the ends folded over. Would have been better if the ends hooked together.
Don't feel bad, it took me two tries to get it right.
Just be careful of the end. The sheet metal forms a complex angle. Trim it too long at first, until the correct angles are discovered. And mind the sharp edges!
The piece of flue pipe is 3" in size. It is galvanized. I would look for some stainless, or even try ABS plastic. I formed it with a wee bit of encouragement from a ball-peen hammer, and a few blocks of wood.
One or two pop-rivets keep it from sliding at the seam. Best place the seam towards the back of the vehicle.
Just 3" Flue Pipe. I added a coat of aluminum paint, but it did not stick right. There is a welding spray, made of zinc, aluminum, and epoxy. I would try that.
Better yet, warm ABS plastic pipe in the oven at 3.25, and jam it on a block of wood for a form. It will cool to that shape, and not soften with normal under-hood temperatures.
Cover the part you don't want to soften with foil. This worked on a similar project. let me know how that works for you.
CrossPlainCrazy, Here is that shot you asked for. Sorry about the delay, I just put it back on for the warmer part of the year.
Cold air pickup looks nice enough. Not stock, certainly. Plenty of cool air with this. Notice that the piece of flue-pipe has been formed from round to square. The junction angle is complex.
Down into the darkness... You can't see the black rubber end very well, but it is the connector. It is the part that goes through the hole, and out the front by about an inch. So, it is supported at this end by the roll of rubber around the end. The rubber has a little taper to it. (Ok guys, no snarky comments...)
In cold weather this gets so much cool air, it overwhelms the warm-air door, and gives too-cold temperatures to the air-cleaner. In high-humidity conditions it would promote carb icing. I'm still working on a solution to that. See warm-air gallery, and snorkel modification if you are interested.
