Improve airflow, increase diesel performance, and enhance towing capability with the K&N NextGen Diesel Dryflow Cold Air Intake System designed specifically for Ram 2500 and Ram 3500 models equipped with the 6.7L L6 Cummins Diesel engine. This high-performance intake system is engineered to deliver dyno-proven gains of up to 19.1 horsepower and 34.31 lb-ft of torque while maintaining your factory engine calibration with no tune required.

The K&N NextGen Diesel Dryflow intake system features a large-diameter, CAD-designed high-density cross-linked polyethylene (HDPE) intake tube with strategically positioned air channels that help increase airflow speed and deliver more air to the engine. The rotationally molded tube design improves airflow efficiency while providing excellent durability for demanding diesel applications.

This intake system includes K&N’s washable and reusable Dryflow LIFETIME Air Filter™ featuring oil-free synthetic filter media. The oversized conical filter design uses a radius-entry inlet to maximize airflow and improve performance while providing up to 99% filtration efficiency. The filter allows service intervals of up to 50,000 miles under normal highway driving conditions and features a convenient two-step cleaning process that requires no filter oil.

The NextGen hybrid airbox features a semi-enclosed design that helps reduce intake air temperatures by shielding the filter from engine bay heat. The enlarged fresh air inlet improves airflow while providing additional protection against harsh diesel operating environments, dirt, and contaminants.

Designed for improved towing and heavy-load performance, the K&N NextGen Diesel Dryflow intake helps increase torque delivery for hauling applications while improving turbocharger airflow and providing enhanced induction clarity without unwanted drone during cruising speeds.

The all-black intake design delivers a sleek, stealthy appearance with an aggressive black-on-black finish that complements any Ram truck build. The precision-engineered components improve engine bay styling while maintaining exceptional filtration and performance.

Installation is simplified with Quick-Lock™ technology, minimal hardware, and a secure sealing design requiring only one hose clamp. The complete intake system can typically be installed in less than 60 minutes.

K&N NextGen Diesel Dryflow intakes are backed by a No-Hassle Lifetime Limited Warranty and are engineered to provide long-term reliability, improved airflow, and enhanced diesel performance. Proudly designed with dedicated customer support, this intake system is built for Ram truck owners who demand better performance, towing capability, and durability.
