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.

5th vehicle to experience a documented 2 to 4% increase in fuel mileage with a K&N. New 2013 Land Rover Evoque went from 26 city/ 31 highway to 28 city/ 33.5 highway. Our other vehicle, a 06 Lexus GS, went from 27 city/34 highway to 29 city/38+ highway, what more can I say, K&N works.

Night and Day I have a 1997 Land Rover Defender 90 and replaced the old dirty factory filter with a new KN filter and it works fantastic. Not only does the motor sound throatier, but the truck really breathes better pulling hills on the highway and comes off the line from a stop with a lot less effort. When I have been 4-Wheeling, I notice very little lag at high elevations and can now tap the gas pedal to get over obstacles much more easily.

Thank you for a superior product, I should have install a KN filter years ago.

All I can say is wow.  I have a 1996 Land Rover Discovery se-7 these trucks are very durable and strong but gas consumption is not one of their good points.  Before I bought the K&N air filter I was getting about 13 mpg town and about 18 mpg Highway with stock Land Rover filters.  Once I bought the K&N air filter my results changed very much.  I now average 16 mpg town and 20-22 mpg highway and I have more horsepower plus on my truck I have 30" tires a steel bumper and steel wheels.  The K&N filters are the best.  My mom has one in her Range Rover and the mileage increased.  K&N makes the best air filters in the world BAR NONE.
