This used Audi water / coolant return pipe, OEM 8E0819373L (also replaces 8E0819373E), is a genuine factory piece removed from a donor vehicle. Designed for the 4.2L V8 (4163cc) in the S4, this tube returns coolant from the engine to the cooling system. A cracked or leaking return pipe can cause coolant loss and potential overheating, making a sound original part a straightforward replacement.
