Description K&N 50-2591 Cold Air Intake System for FORD F-150 (P552)
The K&N 50-2591 NextGen cold air intake system is designed for the Ford F-150 5.0L V8 to increase airflow volume and improve engine performance. The rotationally molded HDPE intake tube delivers a 46.24% airflow increase, supporting gains of 15.22 horsepower and 20.37 lb-ft of torque without requiring ECU calibration. The system includes a washable, reusable High-Flow LIFETIME Air Filter⢠with oiled cotton media, offering extended service intervals under typical highway driving. A custom NextGen airbox helps reduce heat intrusion from the engine bay, and the simplified layout enables installation in under one hour.
