This OEM coolant hose, part number 420121055, is designed specifically for the left front section of the Audi R8 models from 2008 through 2015, including the Base, Plus, Spyder, and GT variants, featuring 4.2L V8 and 5.2L V10 gas engines. The hose plays a vital role in the vehicle's cooling system by facilitating the flow of coolant between the engine and the radiator.
