K&N 57i Series Induction Kit Air Intake

HORSEPOWER YOU CAN FEEL
As with all our kits, when you bolt-on a 57i intake, you will notice the difference the next time you drive your vehicle. Our 57i Gen I Intake Kits are a great way to maximize airflow and engine performance. They will replace the factory air box providing both High-Flow air filter technology and a larger air filter size. This winning combination will increase horsepower and sound great too.

BREAK OUT OF THE FACTORY AIR BOX
57i Series Intake Kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. Each kit is designed to provide power throughout the RPM range.

57i Series Air Intakes Are Street Legal in Most States TECH TALK
These kits bring engine airflow out of the factory box by providing a large size open-air conical or round High-Flow Air Filter. 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 then 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 and ensure long life.

57i Intakes are not legal for use in California and other US States adopting California emission standards...
