The Revotec NACA Duct is the only one of its type to use NACA geometry with a rear ducting coupler to produce an extremely efficient intake which produces as little parasitic drag as possible. When properly installed, it allows air to be drawn into an internal duct at up to 90% efficiency, ideal as cold air induction for cooling brakes, engine components or drivers.
