Audi cabin air intake / HVAC duct OEM part number 4H1819904A is a used genuine part from a donor vehicle. Also referred to as the HVAC duct or cabin air intake, it channels outside air into the heating and ventilation system. This duct came from an Audi A8 Quattro or S8 with any of the available engines (3.0L V6 diesel or gas, 4.0L V8, 4.2L V8, or 6.3L W12). A dirty or blocked duct can reduce cabin airflow, making the HVAC system less effective.
