but of course you can relocate the IAT all the way up to the front bumper if you wanted, its still a method for reading the emperature, just in a cooler spot. so i agree with you completly on how big a factor that all is.
also what i forgot to mention was, running a richer a/f would lead to lower combustion temperatures would it not?

Heat soak in a stock intake system isn't as much of an issue, since the majority of the plumbing up to the TB is plastic/rubber compound. Where you would experience more heat soak in the primary would be for those running metal CAI/WAI's.
Running a little richer does run a little cooler, but too much will also get hotter again, and eventually it will foul the plugs faster as well, not to mention the excess carbon buildup in the combustion chamber. Case in point, when I was working on getting tuned and was set too rich, you should have seen the flames shooting out of my exhaust pipe, since there was nothing to suppress it.
