come on now, he realized he made a mistake don't be one of those guys 
VenomRX7: Thermal coefficients of some metals:
Aluminum .00203 Btu/second
Steel (hard) .00034 Btu/second
Steel (soft) .00062 Btu/second
So that means that Aluminum can absord 3.27 times as much heat in the same given time as soft steel and 5.97!! times as much as hard steel.
This also means that it can transfer that energy to the air passing through it that easily. So it won't feel as hot because the air is heating up inside more so than with steel *given the metal is at the same temp*.
It may be the case however, that since the heat is constantly being sucked away at a greater speed, that heat buildup is not as bad and thus the intake air still stays lower *sounds like a good intake metal*, but my point was originally that aluminum is one of the best heat conducting metals and ... well.. the numbers stand.

hey djhunter.. good job on the intake.. i wish i could find a coupler that size for the back piping on mine but i guess mine will work... did you have any idle probs on that car after you put that on? nice to know somebody did it before me and liked it... thanks for the pic

Guess what intercoolers are made out of? And radiators, A/C condensors and evapotators, and lots of other different types of heat exhangers... Aluminuim is used for all these because of it's excellent heat transfer properties.
But I think getting worried about this for intake pipes is pointless. Most of the time the velocity of the air through the pipe is so fast that very little heat transer actually takes place.

your right nz conv... i do not think this piping will just drastically damage the temperature of the air going thru it... i was looking at the pipe today while workin on the damn idle and noticed it is coated with something and after running the engine for a while getting it warm the pipe on the inside was cooler than the outside so once again it might not be as bad as some are saying

what i did for a freinds probe is take some plastic tubing ran it through his wheel well and down right behind the bumper and i told him whenever he wants some extra horse power put sum ice in the little igloo cooler i put the hose goin through lol we dynoed it and it did add like the smallest thing of hp. lol it was funny
