A used OEM Audi Coolant Hose / Line, genuine part number 4E0121088L, sourced from a donor vehicle. This hose carries engine coolant to maintain proper operating temperature; a failure typically causes coolant leaks and potential overheating. It is designed for the 4.2L V8 engines (EA versions of the 4163CC and 4172CC naturally aspirated DOHC) found in the Audi A8 Quattro. An exact replacement for the original equipment hose.
