Used OEM Audi engine coolant pipe, part number 078121081Q, also known as a front coolant tube or line. This genuine pipe routes coolant through the front of the engine bay on 2.7L and 2.8L V6 engines, including the 2.7L twin-turbo and 2.8L naturally aspirated variants. A cracked or corroded original pipe can cause a sudden coolant leak and engine overheating. This used part was removed from a donor vehicle and is ready for installation.
