About this part

Product Details

The K&N NextGen Diesel Dryflow cold air intake system starts with a high-density polyethylene (HDPE) tube, rotationally molded for a smooth, consistent internal surface. This large-diameter tube is CAD-designed with specific air channels to help increase the volume and speed of airflow heading into your 6.6L diesel engine, which can result in more horsepower and torque without needing an engine tune.

This system includes K&N's washable and reusable Dryflow air filter. Its synthetic media is oil-free, meaning you can go up to 50,000 miles between services under normal highway driving conditions. Cleaning is a simple two-step process, and the oversized, conical shape of the filter maximizes surface area for better airflow. The custom-designed NextGen air box is built to help shield the intake from the engine bay's heat, further ensuring cooler, denser air reaches your engine. Installation is typically straightforward and can be completed in under an hour.
