This used OEM Audi coolant hose (4H0121447S) is the genuine left-side line from a 4.0L turbocharged V8 A8 or S8. Also known simply as a coolant line, it circulates engine coolant between components. A failing hose often weeps at the connection points or causes low-coolant warnings and overheating. This part has been inspected and removed from a donor vehicle, ready for installation.
