all of these CAI's arent realyl CAI's they are still in the engine bay sucking in hot air. Now i did tests a long time ago and after about 3 minutes of driving, your pulling in ambient air temps (within 5 degrees f) but for the guys who race, im not sure what drag race lasts 3 minutes lol.
The only 2 that arent in the engine bay, providing the best temps at all times, are the WMS with heat shield and the Intake KB designed for the S/C cars.
I am sort of toying with the idea of creating a similar intake for N/A guys along the lines of the KB intake. Not that id sell it, but id love to test it.
