With K&N's 57i intake, you will notice the difference the next time you drive your vehicle. The K&N 57i Gen I Intake Kits are a great way and in many cases the only way to maximize airflow and engine performance. The K&N 57i 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.

In any induction kit setup there can be a restriction between the air filter and the engine therefore reducing the benefit of a K&N Panel Filter. The weakest link in the airflow chain robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the Engine.

K&N 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. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each K&N 57i induction kit is designed to provide power throughout the RPM range. 57i Gen I’s take advantage of the added airflow provided by an over-sized air filter released from the restrictive factory air box..

These K&N induction 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 K&N filter is then either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the air filter to the engine. All adaptors are made from high quality materials such as steel, aluminum, silicon or reinforced nylon and ensure long life.
