Extra Air is an installable performance-enhancing component for Extreme Gears. Its actual appearance is unknown, though it is presented as an icon on the head-up display in the top-left corner of the game screen. Its icon is white with the image of a swirl and an arrow inscribed in it.
Overview
In gameplay, Extra Air is a customizable Gear Part that can only be attached to different Extreme Gears. It can be bought from the shop for 250 Rings.
When in use, Extra Air will immediately increase the maximum capacity of the Extreme Gear's Air Gauge, which allows it to store more Air than normal, until the player deactivates it or finishes the race.
If Extra Air is installed into the front slot, it becomes active in gameplay once the race begins. If installed into the rear slot, however, the player can activate, and as well deactivate, Extra Air by switching stance by turning his/her body around due to the Kinect controls of the game.
