This used OEM Audi transmission brace / sub frame, OEM part number 8K1399345E, also replaces 8K1399345C, 8K1399345B, and 8K1399345D. Also called a sub frame, this structural support stiffens the drivetrain mounting area. A failing brace can cause driveline clunking or excessive vibration under load. It fits a range of 2.0L and 3.0L engines across multiple Audi models and the Porsche Macan.
