A used genuine OEM Audi Air Intake Duct Cover (part 4H0129666C) from a donor vehicle. This cover protects the upper air intake tract on 3.0L, 4.0L, 4.2L, and 6.3L V6, V8, and W12 engines found in the Audi A8 and S8. A cracked or missing cover can allow debris into the intake system or cause unmetered air leaks, reducing filtration efficiency.
