A used OEM Audi inner door seal / weather stripping, part number 8Y0831721B. This genuine seal replaces earlier versions 8Y0831721A, 8Y0831721, and 8Y0831721C. It mounts on the front door, fitting either the left or right side. The seal blocks wind, water, and road noise from entering the cabin. Over time, these rubber strips can harden or tear, leading to drafts and leaks.
