This used Audi coolant pipe (OEM part number 4H0121034G) is a genuine right-side line from a donor A8 Quattro. Also known as a coolant tube or line, it routes coolant through the engine bay—a cracked or leaking original pipe can cause overheating or low coolant warnings. This version fits Audi A8 models with the 3.0L supercharged V6 or the 6.3L W12.
