Description
Upgrade your 6.7L Power Stroke with the K&N NextGen Dry Flow Cold Air Intake System, engineered to deliver measurable gains in horsepower, torque, and overall engine efficiency. Designed specifically for Ford Super Duty trucks, this system improves airflow, enhances throttle response, and provides the power needed for towing, hauling, and heavy-duty performance.
This intake system is dyno-proven to increase horsepower and torque while maintaining a smooth and refined driving experience. The improved airflow allows your turbocharged diesel engine to breathe more efficiently, resulting in stronger acceleration and better overall engine performance without excessive cabin noise.
The innovative NextGen airbox features a semi-enclosed design that helps reduce intake air temperatures while protecting against harsh environmental conditions. An enlarged fresh air inlet ensures a consistent supply of cool air, which is essential for maintaining optimal combustion and performance under load.
At the core of the system is an oversized Dryflow® synthetic air filter with a radius-entry design to maximize airflow. The Quick-Lock™ technology simplifies installation and ensures a secure fit using minimal hardware. Unlike traditional oiled filters, this system requires no oiling, making maintenance fast and hassle-free while still delivering up to 99% filtration efficiency.
The large-diameter intake tube is precision CAD-engineered to optimize airflow dynamics. Integrated air channels help increase air velocity and improve volume delivery to the engine, supporting both stock and performance-tuned applications.
Finished in an aggressive all-black design, this intake enhances under-hood aesthetics while delivering the durability and reliability expected from K&N. Built for real-world diesel demands, it is ideal for truck owners who demand both performance and long-term usability.
