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 Intakes are not legal for use in California and other US States adopting California emission standards.

Customer Feedback

Very good with shipping. It arrived on time, but I really do not feel a difference in the performance of the engine of my 2008 Toyota Tacoma. For now, the only difference I've noticed is a change in the sound in the engine. I am happy with the product, I think if it helps the engine, even though I did not feel it.

Great product, better than expected on 2016 Toyota Tundra.

I've have never been disappointed by the quality and value of a K&N filter. I've purchased one for every vehicle I've purchased in the last 25 years. I keep my cars to 200k+, Motorcycles to 80k+, and all sold running well. K&N air filters lowers cost of maintenance, boost performance and efficiency of the vehicle. Acura Legend 290K Toyota Celica 287k, Honda GL1100 91K, Passat TDI 240K, Honda ST1100 89K and Currently Yamaha FJR1300 43K & Toyota Corolla 88K.
