Audi A4 Quattro Air Filter - APR High Flow, Cotton-Gauze, Washable (2009-2016). A direct, drop-in upgrade for the factory airbox that improves airflow while protecting your engine.

APR's proprietary cotton-gauze media is flow-bench tested to reduce pressure drop versus the stock paper element, helping the engine breathe with less effort. The filter is washable and reusable with normal maintenance, works with the OEM intake, and is designed not to affect emissions. Expect crisper throttle response and a modest induction note, especially on turbo models.
