The company that makes them is called Arospeed.The intake is placed right in front of the radiator, so the heat from the radiator is now being radiated to your intake's housing, which of course is then transferred to the intake air. So you'd actually be taking in hotter air than a normal cold air intake would. Second, whatever tiny ram effect it might have(I'm visualizing too much turbulence across the face of the filter to have any real ram effect, since it's in open air instead of enclosed) is negated by the longer tube with more bends, and the air having to take too many 90 degree turns.You'd be better off getting a real cold air intake.The site the guy above posted is the only place I've seen that says it makes more power than an AEM, and even then "they" don't make the claim(so they can't get sued for the blatant lies?) we have to take their word the "customers" are making the claims. Don't waste your money on it...
