K&N NextGen Diesel Dryflow cold air intake systems feature a high-density polyethylene (HDPE) rotationally molded tube designed to help increase the volume of airflow to your engine and provide an increase in horsepower and torque with no tune required. This intake system is paired with a washable, reusable Dryflow LIFETIME Air Filter featuring an oil-free synthetic media. The oversized, conical design allows you to go up to 50,000 miles between filter services under normal highway driving conditions and has an easy oil-free two step cleaning process for convenience. A custom designed NextGen air box helps protect air intake from the high temperature of your engine bay, and the entire system can typically be installed in less than 60 minutes.
- Large-Diameter Tube: The large-diameter, CAD-designed intake tube features strategically positioned air channels that increase airflow, boosting air speed and delivering more air to your engine for added performance.
