My wimpy little half-assed CAI you see in my sig pic makes a 30° difference in intake temps. If I remove my headlight, I get another 10° colder. I played with this for over 2 hours some time ago. Runs of identical speed, up and down the same country road. With and without the CAI, with and without the headlight. This is what drove the idea for a ram-air feed to further overpower any engine bay heat that tried to enter. With my SC gulping air faster than the CAI supply can be replenished, I realized a simple 2 or 3" tube stuck in the air wouldn't cut the mustard. That'* why I'm working on a scoop.

Yeah, but what I'm saying is that if you have a fully air tight CAI with some sort of ambient intake, The air isn't going to spend enough time over the exhaust to really make a difference worth more modding.

With a NA, that may be true. Just make sure you have as much supply as the surface area of the filter needs.

What other factors play in on inducted models? Besides compression heating of course.

Not alot more. Of course there'* the debris factor. I don't want so much as a piece of lint entering the rotors when it'* spinning at 16,000 rpms. I make very sure all connections are secure, and airtight.

It just boils down to the fact that laminar flow is the best for both styles of induction, for slightly different, but similar reasons.
