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 Large size has 2 outlet nipples that accept our 3" duct hose (sold separately). Approximately 10.5" long x 9" wide opening requires a lot of space but delivers huge airflow that can be directed to two separate targets. 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.
