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


AWESOME SERVICE!! Of course, great air filter! This filter is for a 1994 Honda Prelude SI. When I ordered my filter, it was out of stock. In about a week, K&N made a new filter and sent it to me!! THAT ROCKS!!!!!!!!!!

I love K&N
I own a 96 Honda Prelude, a 93 Honda Accord, and a 94 Nissan 4x4. I have K&N filters in all of them. I love K&N! Every time I buy a new vehicle, I get rid of the paper filter immediately. Thanks for the extra performance and mileage!

The upgrade in performance can be noticed instantly However I was not happy with the air filter not fitting into the bike...I would have appreciated the instructions explaining that it needed to be motified to fit the bike. I gave 4 stars based on the upgrade in performance of the bike. 08 Honda cbr600rr
