As said, ambient temps will vary during the day. What's important is the variation during the run. All the ones you pointed out has zero temp variance which means they weren't affected by underhood temps. That's the key point in posting them. It would have been nice to see what the ambient temp was at the beginning of each test but i'm sure the 3k rpm temps were probably close if not dead on them. If you just went by temps, the OEM system had the lowest overall temps. It was also the first test of the MORNING, which means cooler ambient air. That brings up a good point though. The initial run of 372/364 was done with almost 10 degree cooler air than the ADM, CAI, and Halltech. I would think that could easily account for an extra 3-5whp. Yet I digress.
The scoop itself just puts more air into the area around the filter, meaning the intake doesn't have to "suck" as hard to get it.
