Audi A4 Air Filter - APR - High Flow, Cotton-Gauze, Washable - 09-16. This direct drop-in filter upgrades your factory airbox with increased airflow and durable, serviceable construction.

APR's proprietary multi-layer cotton-gauze media is flow-bench optimized to reduce pressure drop versus the stock paper element while maintaining excellent filtration. Washable and reusable with normal maintenance, it's a smart upgrade for B8/B8.5 A4 models (2009–2016), including 2.0T, when you want better efficiency without replacing the entire intake.
