its a diffuser that lets air drag release through the back bumper...worth a good 30hp to the wheelz y0

its called a rear bumper diffuser.. from what i understand, it reduces wind resistance by preventing air from being trapped under the car/ behind the bumper.. it seems like it would work, but i really dont know how much drag the rear bumper actually causes..hope this helps

Mr. Thunderlips

Unless you have a hardcore drag car...Useless and gay mod.

you would think that would help on gas mileage for highway use, less drag is better at 75 MPH or so the less drag you get the better gas mileage you get. but its not really gonna do much for a car thats not below 12's
