Let's think about this...the web site claims that it can move 500 cubic feet per minute (cfm). That's a lot of air for a 12V driven fan.....
For comparison, a 2.2L engine running at 3000 RPM displaces 116 cfm (3000 rpm, 2.2L of air displaced per 2 revs). A typical box fan moves about 2000 cfm on low.....do you really think you're going to move 1/4th the air flow of a box fan with a little fan in the intake? If these things actually worked, why wouldn't the OEMs use them?
I'm betting you haven't actually measured the horsepower increase (or 6.4 second 0-60? come on....), but instead are just trying to get people to buy your product.....
