K&N 57i Series cold air 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 of these kits is designed to provide power throughout the rpm range. The extra surface area of these open-air air filters provides even more airflow at lower restriction than a K&N OEM 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.
