Audi A4 Air Filter - APR High Flow, Cotton-Gauze (2002–2009). A direct drop-in for the factory airbox, built for better airflow and long-term serviceability.
APR’s proprietary cotton-gauze is flow-bench optimized to cut pressure drop versus stock while maintaining excellent filtration. Washable and reusable, it helps the factory intake breathe easier without tuning. Expect crisper throttle response, a touch more induction sound, and on turbo models, quicker spool. Fits 2002–2009 Audi A4 and A4 Quattro; emissions friendly.
