The K&N 57-1557 AirCharger Intake System replaces the factory intake system for enhanced airflow that helps increase performance in your Dodge Ram 2500/3500 6.7L diesel. A high-density polyethylene (HDPE) rotationally-molded tube helps increase the volume of airflow to your engine, and provides an increase in horsepower and torque. These systems are paired with a washable, reusable High-Flow Air Filter featuring oiled cotton filter media. The oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A custom heat shield helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 60 minutes.

Installation Tech Tip:
The Mass Air Flow (MAF) Sensor is installed in the intake tube of the air intake system. During installation of a cold air intake, the MAF must be removed and transferred over. While replacement of a functioning MAF sensor is not necessary, it is considered a good practice to inspect, clean, or replace the sensor (if needed) whenever it's removed.
