K&N's 57S Performance Airboxes

K&N's 57S Performance Airboxes increase horsepower and acceleration by dramatically reducing air flow restriction caused by the original factory design.

They come with K&N's Million-Mile Limited Warranty.

57S series airboxes replace the factory air filter housing with a fully enclosed injection modified air box containing a reusable K&N air filter.

Installation is easy as they are specifically engineered to use factory holes and mounting points. No additional hardware, cutting or drilling is required.

K&N 57i Series Performance Induction Kits

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 adaptors 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.

K&N 57i Series Performance Induction Kits

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 adaptors 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.
