Thanks for pointing this out. It was one of the points I had read in other threads. When it works, a WAI is an easy way to "lower" your HP.

Specifically for my S-Series Saturn, I have read the "hottest" my IAT temp can get is about 180 degrees F (as read by the ScanGauge). Over that, and the car will become undrivable.

On the WAI on my car, I usually see a range between 120 and 140 degrees F while driving in my "ideal conditions". When I am stuck in traffic, I can get over 160 degrees F. I should insulate my WAI (it's just a clothes-drier duct) for better performance, but I am happy with the setup as-is for now.
