Exactly. But my point is that with aluminum's high rate of heat transfer and the engine's high heat output, how effective is the CAI at keeping the air cold?
I would think that the hotter the engine gets, the hotter the air intake tube would get and the hotter the air entering the throttle body would be.
I might be wrong (probably) on this one, but it just seems like common sense to me that rubber is a better insulator than aluminum and would delay the time it takes for the incoming air to reach ambient temps in the engine bay. Which would make the stock setup as good as or better (cheaper too) than an all aluminum intake tube.
