Homemade Cold Air Intakes

Hello;
Does any body try to make a Homemade cold air intake, by using a pcv pipes, or any other kind of tubes?
Well I'm planning to do it, but first I have to buy the cone filter, then some
rubber tubing couplings, but what about the pipe?
Any bidy have any idea?
Well I take some measures and the trottle body inlet is 2-3/4'', thats my real
problem I can't find a pipe with this measure.
Or if any body knows whre I can find it or what kind of pipe may I use?
Thanks
Victor

Homemade CAI

Well I appreciate your advice, but now I ask to everyone, some or may be all of the CAI manufactures, create his CAI with aluminum pipe (tube), maybe
some other metal materials, like stainless steel only a few create his CAI tube
(pipe) of plastic.
Now Aluminum, and metal materials has the property of change his temperature very fast they aren't insulated materials, like maybe plastic do.
So, don't you think the air is passing thru this metal cai is entering to the motor very hot not cold, because the pipe is hot remember that!
I think and everyone can helpme, or refute on this, plastic in this case pvc pipe I think can insulate more the hot temperature than aluminum.

I confronting a problem doing the homemade cai, specifictly with the pipe (tube), I can't find a 3'' exactly pipe, 3'' pvc pipe is not 3'' exactly and won't fit in the coupling ( rubber couplings).
Also I din't find 2- 1/2'' pvc pipe.
I find the 3'' metal pipe from a muffler shop but I'm trying to not to use metal pipe.
But if any body can make me change of mind about metal pipe, well I appreciate advices.

aluminum pipe is typically ideal. personally, i think a laundry dryer duct is cheap and effective, if it wasnt so durn flimsy.

also, aluminum is a very good non-conductor of heat. for example, whenever you cook with aluminum foil, the foil itself doesnt really get hot, except for when its wrapped tightly around a potato or something like that. also, my dad's ladder/lumber rack on his super duty is made entirely of aluminum, and even after sitting all day in direct sunlight its cool to the touch.

Yes aluminum is definitely more efficient in the heat dispersing department, but insulation can make it better. Just use some header wrap insulation on the metal pipe and you'll be fine, though I've never heard that you can't use PVC pipe because it releases a poisonous gas. I've heard of people using PVC while making intakes all the time. Maybe if you REALLY heat up the PVC? It won't get that hot anyway. I'm sure there isn't even a problem if you paint the PVC pipe like most people do anyway...

intake why don't you get 3" pipe and use or make a rubber gasket you only got a 1/4" difference to make up for

You would have to get it so hot it will liquify to produce toxic fumes

I would stick to metal and make a heat shield wrapped in aluminum shiny side towards the heat
