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.

I like your products. I have 3 vehicles; a Mazda Miata, a Toyota Tacoma, and a Harley soft tail, and all three have your air cleaners. I also use your KN-171C oil filters on the Harley.

I used the same K&N drop-in filter on my 1990 Eagle Talon TSi AWD from 2002 to 2007, when I sold it.  The new owner of the car is still using the filter I purchased years ago.  I'm now using K&N air filters on my 1993 Mazda Miata, and my 1991 Mitsubishi Galant VR4.  It has made a night-and-day difference on the Miata, especially in low-end torque.  On the Galant, I now hit boost 200-300 RPM sooner, and I can definitely feel the difference in power.  Not only are K&N air filters proven to perform, they are also built to last.

Plus, K&N oil filters always have a nut welded on to the end of each filter.  As someone who changes my own oil, that's a godsend.

I bought this filter to see if I could increase my mileage. I was shocked at a 10% increase in MPG. My 2013 Accord V6 manual was getting 27-28 on the Hwy with the stock air cleaner. When I put in the K&N filter I am now getting 31-32 MPG. I once tried to drive real easy just to see how good I could get for mileage and once got 34.3 MPG. This car doesn't need any more power at almost 280 horse it's almost too much for front wheel drive, but it's fun when you want it. Highly recommend this product. Oh I even put a K&N filter in my wife's 2014 Mazda 6 and have seen similar results. Great filter. Again highly recommend.
