Medium NACA Duct (1 Outlet), for 3" Hose

Our NACA ducts were designed and wind tunnel tested for maximum air flow with minimal drag. They are molded from tough, high-impact plastic. An integral flange (approximately 3/4" wide) makes them easy to rivet to body panels or bond to composite panels with epoxy.

This Medium size has an outlet nipple that accepts our 3" duct hose (sold separately). Approximately 9.5" long x 4.5" wide opening is just right for most applications such as air dams or side windows. Choose Clear or paintable Black plastic. Sold individually.

Note: These ducts are designed and built for racing use. They are not built for show cars. You can sand and paint them, but do not expect a "show-quality" finish out of the box.
