K&N High-Flow Engine Air Filter for Audi A1/A3/Q2/Q3/TT (33-3005) — Washable, Reusable, Pre-Oiled

Built to replace disposable paper filters, this K&N high-flow replacement filter uses layered cotton gauze media to let more air reach your engine while trapping dirt and contaminants. It fits directly into the factory air box and arrives pre-oiled so you can install it in minutes. Backed by K&N’s limited lifetime warranty and decades of motorsport testing, the 33-3005 aims to combine longevity, environmental savings, and measurable performance improvements for everyday driving.

How much performance change can I expect with this filter?

The 33-3005 is designed to increase airflow compared with many stock filters, which can translate to improved throttle response and, in some vehicles, modest horsepower gains. Results vary by model, tune, and surrounding intake setup, but the filter’s media prioritizes flow without sacrificing particle capture.

• Optimized multi-layer cotton gauze for higher airflow
• Engineered to work in factory airbox configurations
• Potential for quicker throttle response depending on vehicle
• Tested under performance conditions for consistent results

How often do I need to clean and maintain the filter?

Under normal highway driving, K&N recommends cleaning the air filter roughly every 75,000 miles, but frequency depends on road conditions. In dusty or off-road environments you’ll need to inspect and clean it much sooner. Cleaning is straightforward using K&N cleaning kit products and the filter is designed for many clean-and-reuse cycles.

• Typical service interval: every ~75,000 miles in average conditions
• Visually inspect sooner in dusty, construction, or off-road areas
• Clean and re-oil with K&N service kit for best longevity
• Reusable design reduces recurring replacement cost and waste
