You're looking at a genuine used Audi coolant pipe, OEM part number 4G0121481AP. This coolant tube/line was removed from a donor vehicle and is ready for install. It routes coolant through the engine bay on Audi A6 and A7 Quattro models equipped with the supercharged 3.0L V6 (2995cc, DOHC). A cracked or leaking coolant pipe can cause overheating or low coolant warnings; this direct OEM replacement restores proper flow.
