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.

The product (PS-1008) and the mailing service are both excellent.  I get better acceleration, the oil stays cleaner longer and I end up having more fun driving my Smart Car.  I also really like the air filter cleaner with also improved my acceleration and mileage.  Thank you for a job well done.

After installing a K&N air filter in my 2008 Smart Fortwo I noticed less hesitation during close navigation such as in parking lots and crowded neighborhoods where low speed movement is crucial.

I also noticed a slight improvement in acceleration.

I recently bought a K&N air filter for my 2007 Smart fortwo dsl.

The filter gave the car better power and throttle response, exceeding my expectations even for an engine of 45 horsepower.

Good work done by K&N

Thank you all
