A genuine OEM upper radiator air duct from a donor Audi, part number 4D0121343A. This used duct directs airflow to the radiator on Audi A8, A8 Quattro, and S8 models equipped with 3.7L or 4.2L V8 engines (DOHC, naturally aspirated). A cracked or missing duct disrupts cooling efficiency, potentially leading to engine overheating under load.
