Audi 4H0121485AC Lower Coolant Line / Pipe, a genuine used OEM part. This right-side coolant pipe was removed from a donor vehicle. It services the 4.0L turbocharged V8 found in certain Audi A8, RS7, and S8 models. The pipe circulates coolant between engine components; a cracked or leaking line can cause overheating and coolant loss.
