Used Audi strut tower brace, OEM part number 8W0805646B, also replaces 8W0805646. This right-side brace connects the strut towers to stiffen the chassis, reducing flex during cornering and improving steering response. A worn or missing brace can cause vague handling and increased body roll. This genuine used part is from a donor vehicle.
