AC Autotechnic has released one of our favorite rear bumper diffusers that are not only functional but offer that hard core race look. Each AC Autotechnic bumper diffuser is made from a high quality CNC machined aluminum cast, and is very easy to install. This rear diffuser is universal and can fit on any rear bumper, but depending on the application it could require heavy modification. Normally this is designed for the Honda and Acura drag cars, drift cars, and any car that wants to allow the wind flow from under the car to escape through the bumper rather than allowing the bumper to be a restriction.

Don't make your own holes in your rear bumper to allow the air to pass through... use a high quality bumper diffuser like this polished unit from AC Autotechnic. Redline Motive is an authorized distributor.
