Cannot Find Engine Sound Mod

hello Beamng drive community! I am having a problem with finding my engine sound mod that i installed. I put the mod straight into the mods folder in the directory, but cant seem to find it in game. What I can find though is in the repository. It says its in the game, where you can deactivate or uninstall the mod, but whenever i try to swap engines, I cant find it. Any help will be greatly apreciated
