I just conducted some temperature testing. I updated the review with this information, but for those who are too lazy to go back and read, I quoted it here
Keep in mind, lower is better. The lower the number, the closer to outside temp.

Here is a graph showing the idle temp climb over a period of 5 minutes. It compares the delta (difference between IAT and ambient), rather than raw temps, to get a more accurate idea of how heat soak will affect the IAT's at idle. Since the aFe is a true CAI, it registers a lower delta up until about 2.5 minutes. Since the AIRAID has a larger filter box, it's temperature progression is less aggressive than the aFe unit; it doesn't heat soak as fast.

Temperature wise, aFe is a much "cooler" intake. Both intakes are branded as CAI's, while I'd technically consider the AIRAID as a LWAI or Luke Warm Air Intake. As you'll see by my graph of a full 3rd gear pull, the aFe registers a much lower temperature delta (the difference between the IAT and ambient temp), which is compounded by the fact that AIRAID locates the sensor in the filter box, where the air would most certainly be the coolest. aFe locates the sensor on the final stretch of piping right before the throttle body.
