Item Lock: 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 a dark pink-colored circle with the image of a pink Item Box containing a pink swirl inscribed in it.
In gameplay, Item Lock: 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, Item Lock: Air will influence every Item Box the player touches, except for Item Boxes that are set to a specific power-up, to only grant Air, making it useful for the player if he/she constantly uses Air throughout a race. Sometimes, the player may obtain two Air items at once from an Item Box.
If Item Lock: 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, Item Lock: Air by switching stance by turning his/her body around due to the Kinect controls of the game.
