The 57-1556 features a special molded plastic intake tube and a large open element conical air filter. The filter sits behind a powder coated steel heat shield which helps isolate it from the rest of the engine compartment. The factory fresh air duct is reused and helps direct cooler outside air toward the filter. This combination allows for a steady supply of unrestricted airflow to reach the Nitro's engine providing an instant performance gain with no other modifications necessary.

The chrome top of the large RF-1042 air filter adds a touch of class when opening the Nitro's hood. The filter stops dust and dirt by using multiple layers of cotton and 1.45 oz of K&N filter oil. This high flow technology invented by K&N provides the best balance of airflow and filtration. The RF-1042 is also washable and reusable, and can go up to 100,000 miles before cleaning is necessary.

The 57-1556 can be easily installed in 90 minutes or less with only a socket set, flat blade screwdriver, and a 10mm wrench. Photo illustrated instructions are included to guide you through the installation step by step. The entire system is backed by K&N's Million Mile Limited Warranty.
