Want to change your engine sound on the fly? This menu lets you set a live engine sound on any vehicle you're driving in-game, for yourself and everyone around you to hear. Open it anytime with your keybind (K by default, changeable in your settings).

You get a total of 19 custom engine sounds to choose from. It is not a permanent change to the vehicle, if the car is deleted or a server restart happens, the sound is set back to the default.
