A used genuine OEM Audi Air Cleaner Filter Box / Housing - Lower Half, part number 078133837BG, also supersedes 078133837AJ and 078133837AN. This lower housing seals the air filter element, preventing unfiltered debris from entering the intake. Cracks or broken mounting tabs on these factory V6 units can allow dirt bypass, triggering a check engine light from unmetered air. Designed for the 2.8L 2771CC V6 DOHC naturally aspirated engine found in several Audi and Volkswagen models, this used OEM housing restores the intake tract's integrity without aftermarket fitment issues.
