Well like many of you my intake ducting was falling apart. After Superstition 10 it was pretty much hanging together by a thread. I figured now is a good time to replace it. I went to Home Depot and did some shopping. What I put together is not "perfect". In fact, I might just get a new tube, heat it, and custom bend it just for fun but this is working very well.
I was looking for something plastic because metal conducts heat very well and that heat is exactly what I want to keep out. Also, plastic doesn't conduct sound like metal.
As soon as I drove off I noticed what others have echoed, better throttle response and in my case better acceleration. I notice the improvement in partial throttle driving range we where spend most of our time. And it's not falling apart! It could be more aesthetically pleasing but for $28 and some change, it's good to go.
The parts all from Home Depot:
(1) 2.5" gray PVC electric conduit tube with a 45 degree bend. One end was flared, or had a "bell" which I cut off.
(2) 3" to 2" rubber reducers located in the plumbing section next to the black sewage stuff
(2) 2" to 2" joining collars in the electric conduit section
(2) .5" barbs, any thread will do, in the... I forget section
Here are two shots of the rubber reducers. They don't fit too well so you have to push kind of hard to get them on but they work.

These are pictures of the pipe cut down and the two collars. The collars resize the pipe so it will inside the reducers. I could not find a reducer or other rubber part that would accommodate the pipe. The second pic as the fittings. I used a tapered reamer to enlarge the holes enough to thread the fittings into.

Here are the fittings installed with JB Weld.

Here are the insides of the pipe where I took down the fittings with a die grinder. I mean you gotta have smooth flow right?

Here is the setup installed. I used JB Weld when I tapped the stuff together so it won't leak or come a part.
