Somehow that info is misrepresented or you're taking it out of context.
If you stick a 300cfm intake on an engine that can only ingest 250cfm at full power, and in so doing it's now taking in that air from a warmer area, then yes it would be a negative; but that would be silly (although that concept gets sold to the unknowing car enthusiast all the time)

But, suppose an engine is capable of ingesting more than the so-called undersized 250 cfm original intake (therefore lower pressure in the intake manifold at full power). Now the aftermarket can supply a 300 cfm intake, but in so doing can only have access to air that's warmer than ambient. In that case the warmer 300 cfm should be used, because having full ambient pressure available takes priority over lower pressure, colder air.

So no; having full air flow available (CFM) is more important than deviations in intake temps.

Basically the higher flowing CAI, but did not access colder air as well, made LESS hp on the dyno than the other. And they tested about 5 or 6 different CAI's.

I can try to find it but it was a long time ago in one of the auto mags.

"because having full ambient pressure available takes priority over lower pressure, colder air."

Not sure about that, as colder, denser air always makes more power. If not a forced induciton wouldn't work. lol The density of the charge air is directly proportionate to the hp.

You're missing the point that the pressure is the biggest part of the density.
To illustrate: your engine will make a lot more power at the bottom of 110 degree death valley, than it would on top of insane cold Mt. Everest
