BMW E36 Hood LouversAluminum E36 Hood Vents are designed to dramatically improve engine cooling capabilities while also reducing under hood pressure. This means less worrying about overheating when you push your car to the limit, with an increase in downforce as an added bonus! This kit was designed with pressure mapping to ensure maximum airflow. The shape of the vents are designed to match the body lines, so they won't look out of place on a track or street driven car.
