Its the most ridiculous thing Ive ever seen. It places the air filter where contamination is very high their way to stop water entry is idiotic and the piping...have you seen the piping length on that sucker? Oh...and lets not even get into the price for that piece of shit. Basically its appealing to a load of ricers who wish they could afford a turbo but still want the look...if you can call that filter the look. And as for a ram-air effect if that was the case there would be some type of cowl to catch the air instead of a filter there to disperse it over the area. Bleh just believe that its a piece of shit and youll be fine.
