The aluminum tube on CAIs does not cool off the incoming air b/c it's as hot as everything else in the engine bay and the extra diameter adds almost nothing to horsepower. 1, maybe 2 on an NA Honda. So for $50 I get about 4 or 5 wheel hp and $150 gets me about 6 (I haven't dynoed this setup b/c it's not worth running an LS on a dyno, especially one that's as close to stock as mine. So my numbers are guesstimates). Iridium plugs gave me more power than the pretty tube. And I saved at least $100 in parts.
Sorry to get off topic like that, but I need to defend my rat rod for a minute.

CAI's on most cars will suck air thats further away from the engine thus cooler - that being said you're right the aluminum does not cool things off so you can do as my buddy did and manufacture your own out of PVC pipe if you had the time to.
SRI's will typically be closer to the engine however when your car is moving cold air is seeping under the hood quite quickly so in most cases I doubt there would be a drastic difference between the CAI and SRI.
My idea - wrap your CAI with refrigerator insulation tape - in theory it oughta keep the cool in and the hot out, I am doing the same to my fuel lines (except I know it works with fuel lines) - anyone have any thoughts on that?
