Our Ventilators can be used almost anywhere your vehicle needs aerodynamic pressure relief. These air pressure vents let you release pressure or hot air from places like: wheel wells, engine compartments, trunk, cockpit, and basically anywhere unwanted heat or pressure accumulate. You can mount these things almost anywhere on many different vehicles since they will conform to all but the most curvaceous surfaces. Our fender vents can even be mounted backwards and used for small scoops. They are cast in black high temp urethane and are very easy to install. The Agent 47 Ventilators come with a drill template and mounting screws. The only special tool that you will need is a 3" hole saw.
