Description K&N 57-3101 Performance Air Intake System for CHEVROLET Silverado 2500 HD 6.6L

An enclosed air box design helps protect the filter and inlet air from engine bay heat. The air box lid allows for quick and easy access to the filter without tools.

A high-density polyethylene (HDPE) rotationally-molded tube increases the volume of airflow to the engine and provides a guaranteed increase in horsepower and torque. The system includes a washable, reusable High-Flow Air Filter with oiled cotton filter media. The oversized, conical filter design allows up to 100,000 miles between filter services under normal highway driving conditions.

Typical installation can be completed in less than 60 minutes using simple hand tools.
