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 provide even more airflow at lower restriction than a K&N O/E replacement filter which is always 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 Intakes are not legal for use in California and other US States adopting California emission standards.

Be the first to review part 57-0618-1
The air filter is so much better than the standard air filter I had fitted. My Audi TT seems quicker and more responsive. I would also like to add, the gent I spoke to over the phone was very professional, helpful and well spoken which made a nice change. If I could I would of given K&N 6 stars. I am also very happy to not have to buy another air filter for my car.

Great drop-in filter for Audi A3 that bumps up fuel economy a bit and performs extremely well compared to disposable filters.

This is not my first K&N product. I have always used them in all my cars (from 3 different Corvettes through Audi TT and just about everything inbetween). Always had great service from them, parts always fit like a charm, and they work and sound great. Would recommend them with no problem.
