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 started using this filter. I ordered from your shop at my first oil change for my BMW G650GS as it's not a common part locally. Since then, I've never bought anywhere else. Always quick delivery, correct item, good price and no hassle. I hope you keep this product in your line-up and thanks for good service over the last +34,000 miles.

I installed this filter in my 2008 BMW 528i in under 2 minutes from hood-up to hood-down. After starting the car in the garage I didn't notice any real difference in the sound but once I started driving it I could hear and feel the difference, especially in sport mode. And as an added benefit, it looks like my fuel economy has improved by about 1 mpg. According to the car's computer, in the 1,200 miles since I put it on, my average economy has gone from 25.2 to 26.2 mpg. Very happy.

Great product. I got rid of the stock airbox on my 1993 BMW 740i. This filter fit right on the open intake hose. I have had it about 3 years and it instantly improved throttle response and the engine sounded better.
