Description K&N 57-0593 Performance Air Intake System AUDI A4 L4-1.8L F/I, 2000-2004

K&N 57i Series induction kits are specifically engineered for each vehicle to eliminate the size restrictions of the factory air box. These kits are designed in various forms depending on vehicle characteristics and available engine bay space.

Each kit is intended to deliver power across the RPM range. The open-air filter provides increased airflow with less restriction compared to a K&N O/E replacement filter, which is limited by the factory air box. The larger filter also captures more dirt, extending service intervals up to 100,000 miles before cleaning is needed.

The filter may be attached directly to the carburetor or throttle body, or indirectly via a tube assembly. All adapters are constructed from high-quality materials such as steel, aluminum, silicon, or reinforced nylon for durability. 57i Series Intakes are not legal for use in California or other states following California emission standards.

Note: Not legal for highway use in states adopting California emission regulations.
