What it actually does is it creates a spiral, twister like air going into the combustion chambers resulting in an more efficient air-to-fuel mixture and much more efficient fuel burning. This can increase your mileage up by as much as 15% and get you some small horsepower increases at the same time. Well if you don't believe me there is dyno graphs to prove it at tornadoair.com. But you don't have to buy it from them, you can make it yourself and believe me it's not that hard. I made mine out of an aluminium can. Go to tornadoair.com and get your idea.
