The E9x hood vents were designed to bring efficiency to the cooling system while providing front downforce by evacuating high pressure air under the hood. Both function and form were considered in the design process, and the vents compliment the lines of the car.
Water temperatures can drop as much as 15 degrees Fahrenheit on a warm day. For cars with adjustable rear wings, it may be necessary to add more angle to compensate for the additional front downforce for optimal balance.
These vents also feature an optional gurney flap for maximum air extraction and drag reduction. The gurney flap creates a low pressure area above the first few slats in the vents to make them even more effective. A must have for track cars!
Vents ship flat and in bare unfinished aluminum. They can be bent by hand to the desired angle. They can be mounted above or below the hood, and it is recommended to paint the vents to your desired finish.
