Well , If you drive 50 miles one way to work and its 95 degrees outside and the engine runs at 190 and just general heat from the engine it would seem that the CAI tube up to the throttle body would heat up as well to temps above the outside air.
seems that way doesn't it?
All I'll say is this. This past march I witnessed a '11 Mustang GT hit 170mph in the standing mile. With a stock air box. Engine running "normal" temps, but with ALL front grill/fascia/whatever openings
blocked off.
Completely. Ran the same with the stock CAI airbox/tube as with name brand monkey CAI kits. Once you capture the grandeur of the whole scenario, it makes you take a step back and realize how silly it is to be monkeying with truly utterly silly things. You have to have serious underhood temperatures via turbos or something to justify 1500°F header wrap on an intake tube. And if you could justify it with twin turbo's under the hood, you'd likely have enough money to ceramic-coat an intake tube to hell and back as well so that ugly a** header wrap would be not an option, lol.
Oh and I've actually datalogged the air temps straight from the PCMs Direct-Memory-Reads. Guess what? Once you actually start moving at a decent speed, the temps do indeed stabilize to ambient temps. Testing reveals all.
