A used OEM left coolant hose for the Audi A8 Quattro, OEM part number 4H0121400S, sourced from a donor vehicle. This Coolant Hose / Tube / Line routes coolant through the engine bay, and a failed hose typically causes visible leaks or overheating. Designed for the 3.0L supercharged V6 (2995cc), it connects critical cooling system components. Make sure your replacement matches the original routing and clamp locations.
