The NACA duct was designed in 1945 by the National Advisory Committee for Aeronautics, a federal agency that laid the groundwork for NASA as we know it today. NACA engineers initially designed the duct as a way to feed air into an airplane engine without adding an excessive amount of drag, but it was seldom used because it provided a very limited amount of airflow.
The Boss 302S is built by Ford Racing, together with Watson Engineering, as a ready-to-run road racing car. The basic specs are aimed at Pirelli World Challenge GTS class racing, but the car is also suitable for SCCA and NASA club events. In the world of factory racecars, the Boss 302S is relatively affordable at around $89,000. Ford builds 50 cars per year, so while they are ordered through Ford dealers (as a part), orders must be placed in time to get an allocation slot and before the annual winter batch build.
