A used OEM Audi coolant pipe, part number 4E0121399L—this genuine tube/line was removed from a donor A8 Quattro. Designed for the 4.2L V8 engine (4163cc or 4172cc), it routes coolant between the engine block and radiator or heater core. When this pipe develops cracks or corrosion, you may notice coolant dripping beneath the car or the engine running hotter than normal.
