Used OEM Audi Coolant Hose / Line 4E0121107D, removed from a donor vehicle. This genuine coolant hose carries engine coolant through the 4.2L V8 (4163CC or 4172CC) in the Audi A8 Quattro. Also known as a coolant line, it is prone to cracking and leaking over time, which can cause coolant loss and overheating. Install as a direct replacement for the original hose.
