This used genuine OEM Audi coolant hose (part 4G0121056J) is the factory-engineered line for the 4.0L twin-turbo V8 in Audi RS7, S6, and S7 models. Also called coolant line, it carries engine coolant between components. When this hose fails, typical symptoms include visible coolant leaks, low coolant warnings, or engine overheating. It was removed from a donor vehicle in good condition—ready to replace your worn or leaking original.
