Product Description
The K&N 33-2209 is a washable, reusable replacement air filter for compatible 2000-2010 Audi A4 applications. It installs in the factory air box in place of the disposable paper filter, keeping the stock intake layout while providing K&N’s oiled cotton gauze filter media.
For an A4 owner who wants a simple intake service upgrade without changing the factory air box, the 33-2209 is a practical choice. Once the filter is due for service, it can be cleaned, re-oiled, and reinstalled instead of replaced. The filter is backed by K&N’s No-Hassle Lifetime Limited Warranty.
Product Video
This K&N video explains how its washable, oiled cotton air filters are designed to replace a factory panel filter and be serviced for continued use.
Before You Buy
The 33-2209 is an oiled cotton filter, so use a K&N filter-care kit when service is due. Do not use compressed air to clean the media, and do not over-oil the filter. Confirm the vehicle’s engine, drivetrain, and factory air-box configuration before ordering because the 2000-2010 A4 range includes several chassis, engines, and market-specific applications.
