why would you want it up front...
that moves it away from the point of combustion...
you want the IAT as close to the combustion point as possible without being effected by the combustion heat itself...
example...
at the front of your car...on a cold day... IAT see's 30*
but the air that goes into your intake is at 55* because of the heat of the engine bay...
now you have inaccurate fueling because of bad IAT placement
if you have it just past the Throttle body...
that 55* air is going to be seen by the IAT and your fueling will be corrected properly.(assuming you have the tune dialed in correctly)

Moving IAT I agree! I always enjoy when measurement/test procedures are modified to get desired results. [bracketracerZ28] Do you work for climate researchers at the East Anglican climate center?

I have the FIPK kit with the free ram air mod and it works great, just cut a hole in the sheet medal radiator support that comes with the FIPK kit under the filter and the air comes up past the radiator through the hole you cut to the filter. Sure when you are sitting still you will get some heat from the motor but when moving the air coming in is fresh. I can't say for sure if it is faster than a lid or not, ( I had a lid), but with the FIPK when I first installed it I could hear the air rushing in the TB at WOT so louder is better right?
