No lessons intended, just wondering if our testing is flawed due to the great difference in ambient. The IAT sensor in the N/A is in the MAF (unlike my Honda-waaaay at the end of the intake mani) and is a good indicator of thermal increase just from the piping/plenum/method of getting the air from outside to inside.
Since I no longer own an OEM box, I can't help here. BUT, I would be interested in seeing your observations once the weather gets hot again.
Alaxfire says he sees 105 cruising and I agree with that, but at what ambient? This is the true indicator, as I see it, of how efficiently, in terms of heat uptake an intake system is, apart and separate from flow.

That's a whole different discussion...
