Electronic adapter for the air device (vacuum) that connects to the lighter. The parts are brand new, I only used them for about a month, and you have the right to inspect before taking them. I will connect it for you and test it in front of your eyes 👍🏻 The adapter size is 3 inches, with two adapters included. It comes with the device (vacuum) and two remotes, all are new and still in their packaging. The hoses are included; the piece is complete and all original with conditions. It is compatible with all types of cars.
