This Audi coolant hose (OEM 8K0121081BK) is a genuine, used part removed from a donor vehicle. Also known as a water hose, it routes coolant through the 3.0L supercharged V6 found in the A4 Quattro, A5, A5 Quattro, S4, and S5. A cracked or collapsed hose can cause coolant loss and engine overheating, so inspect the rubber for brittleness before installation.
