Huge waste of money. 1st of all there are outlet ducts directly behind the inlet of the scoop (in other words all of the air that enters the scoop goes directly out the back instead into the intake system). After I received the scoop I tried to get information online as to why the air is designed to straight out of the back of the scoop and found that Banks claims that they are supposed to keep rain out of your intake. I noticed absolutely no increase in power or gas mileage. Save your money!!!!
