K&N 57i Series Performance Intake Kit for Audi A4 1.8L Turbo, Part Number knn57-0593

K&N 57i Series induction kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provides even more airflow at lower restriction than a K&N O/E replacement filter which is limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Series Intakes are not legal for use in California and other US States adopting California emission standards. K&N's 57i induction kits are easy to install, economical, and come with K&N's No-Hassle Lifetime Limited Warranty. They consist of a large washable/reusable K&N air filter with adapters for connection to the engine's throttle body.

Free your Audi A4 1.8L Turbo from the airflow limitations of the factory air box with the K&N 57i Series Performance Intake Kit, part number knn57-0593. Designed specifically for compatible Audi A4 applications, this induction kit uses a large washable and reusable K&N air filter to provide increased airflow with less restriction than a replacement filter limited by the factory air box. The intake is engineered to support power throughout the engine’s RPM range while maintaining a practical, vehicle-specific installation.

The larger filter offers increased surface area for airflow and can capture more dirt before cleaning is required. With proper maintenance, the filter can remain serviceable for up to 100,000 miles, depending on driving conditions. High-quality connection components are selected for durability and may include steel, aluminum, silicone, or reinforced nylon materials based on the vehicle application. The kit is designed for straightforward installation and includes the components needed to connect the filter assembly to the engine throttle body.

Fitment includes select 2000, 2001, and 2003 Audi A4 and Audi A4 Quattro models equipped with the 1.8L Turbo engine rated at 150 horsepower. Verify the vehicle year, drivetrain, engine configuration, and existing intake arrangement before ordering.
