For an Audi A6 Quattro with the 4.2L V8, the engine air filter box upper half (OEM 4F0133837AT) is a used genuine part. This upper housing covers the air filter element and directs airflow into the intake system. It also replaces part numbers 4F0133837BA, 4F0133837D, and 4F0133837E. The box is specific to the 4163cc and 4172cc naturally aspirated V8 engines. A cracked or broken upper half can allow unfiltered air into the engine, affecting performance.
