Air Plus 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 with three sparkles inscribed in it.
In gameplay, Air Plus is a customizable Gear Part that can only be attached to different Extreme Gears. It can be bought from the shop for 400 Rings.
When in use, Air Plus will increase the maximum amount of Air an Extreme Gear gains when the player performs successful Air Tricks by 33% until the player deactivates it or finishes the race. The air bonus is additive. For example, using it with the Potential (which reduces Air earnings by 30%) means the player will earn 103% of the normal amount of Air they would get in normal circumstances.
If Air Plus 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, Air Plus by switching stance by turning his/her body around due to the Kinect controls of the game.
