From the Super Mario Wiki
The Swooper (known as the Swoop in Europe and Oceania) is an unlockable glider part in Mario Kart 7. As its name states, the Swooper is shaped like the Swoop enemy. It offers an acceleration boost, while hindering weight, but like all the other gliders, it allows karts to go airborne for a brief time period. It has the same stats as the Paraglider.
