Medium NACA Duct, Single Hose
Computer Aided Design (CAD) and wind tunnel testing have been combined to produce these NACA ducts. Attention to detail results in maximum air flow with minimal drag. They are molded from tough, high-impact clear or black plastic. An integrally molded flange (approximately .75" wide on most ducts) makes them easy to install in body panels, air dams or side windows. They can be mounted in place using rivets or bonded with epoxy. The outlet nipple is sized to fit our 3" air ducting hose. Approximately 9.5" x 4.5" opening excluding flange.
