Genuine Audi Air Filter Engine Air Filter 4H0129620L OEM A8 S8 - Audi (4H0-129-620-L)

Genuine Audi OEM Air Filter is a genuine Audi replacement part designed to keep your A8's engine breathing cleanly and performing at its best. This filter fits the Audi A8 equipped with the 3.0L and 4.0L engines, covering both gas and diesel configurations, excluding the S8 and S8 Plus variants. As your engine's first line of defense, the air filter traps dust, debris, and contaminants before they can reach sensitive internal components like pistons, cylinders, and fuel injectors. Choosing a genuine Audi OEM air filter over an aftermarket alternative matters because the filtration media, fiber density, and frame dimensions are engineered to exact factory tolerances — ensuring the correct airflow balance your engine management system expects. An ill-fitting or imprecise aftermarket filter can disrupt mass airflow sensor readings, reduce fuel efficiency, and accelerate engine wear over time.
