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.

Customer Feedback


Couldn't believe how restrictive the original equipment air filter was . After installing the K&N replacement , the motor seems smoother and more responsive . The great gas mileage of my Subaru appears to have improved also .
Leonard Costrino, Darien Center New York
No vehicle I've owned since 1990 has gone without a K&N air filter ... period. In my opinion, it is one of the most - if not THE MOST - cost-effective aftermarket replacement part anyone can add to boost performance and fuel economy. This filter went into my new Subaru Crosstrek Hybrid and, just like always, the difference in performance and mileage was noticeable and immediate. Thank you, K&N, for your great products!

Great experience working with your company. It was easy to find what I needed and order on your website. The product shipped quickly and arrived on time. We purchased an air filter for our Acura RDX and our Subaru Outback. The filter fit perfectly and my Acura RDX has never run better. I loved your Stop label that I can put on the filter box. Thanks so much.
