Audi Air Cleaner Filter Box / Housing - Upper Half OEM 078133837BG, a used genuine part from a donor vehicle. This upper half of the air filter enclosure, also known as the air cleaner housing, bolts onto the lower section to seal the filter element. It replaces numbers 078133837AJ and 078133837AN. Designed for the 2.8L 2771CC V6 gas engine (DOHC, naturally aspirated) found in Audi A4 and A6 models as well as the Volkswagen Passat. Cracks or broken mounting clips on this housing can allow unfiltered air into the intake, reducing engine protection.
