OBSERVATION ON CAIs
I re-connected my Scangauge to the system and made interesting observation.
According to my outside temp gauge in the mirror and Scangauge sensors (read - ECM sensors) there is only 3 degrees difference between the OEM intake air temperature and ambient one. THREE DEGREES. that's it. So, why are CAIs called "cold"? Can't make it any colder than ambient air and 3 degrees is negligent difference.

Re: OBSERVATION ON CAIs
The ones we have for our trucks are ram air, not cold. Cold are the ones on like my integra that goes down by the front bumper and sucks up water when you hit a puddle.

Re: OBSERVATION ON CAIs
Because the air is colder than the air in the rest of the engine bay, which is nowhere near ambient.

Re: OBSERVATION ON CAIs
I've been running a cold air intake since last October. My fuel mileage has actually decreased.
Around here, all vehicles have cold air intake between October and April, and fuel mileage is always worse in colder weather.
