The K&N NextGen Diesel Dryflow Cold Air Intake is a cold air intake for the 17-19 Ford F250/F350 SD with the 6.7L diesel engine. The kit combines a rotationally molded HDPE intake tube with an oil-free synthetic DRYFLOW filter, which K&N lists for up to 50,000 miles between filter services under normal highway driving.
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. 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.
Features
- Engineered for Convenience: NextGen Dryflow® synthetic media delivers up to 99% filtration efficiency and features an easy, two-step cleaning process that requires no oil, making maintenance more convenient.
A cold air intake replaces the factory air box and intake tube, routing air through its own filter to the engine's throttle body from a spot away from engine heat.
