I have a hood kinda like that but I'm sure it's nothing special lol. The air exits out the front and the hood is raised up in the rear and it exit's out rear vents at the very end of the hood. I got it to help keep my engine bay cooler, bad part is it's dirty as shit right now lol. Car was parked in the desert at my friends shop for close to 2 years. It looks like the desert wants to calim my engine bay back lol.
