Product Description

The K&N 70-2591 is a NextGen Aluminum cold air intake system engineered for the 2016-2020 Ford F-150 equipped with the 5.0L V8 engine across all trims and cab configurations in both 2WD and 4WD. Part of K&N's newly released 70-series NextGen Aluminum lineup, this intake uses a rigid 6063 American aluminum tube to deliver up to 67% more airflow than the factory intake assembly - producing gains of up to +14.6 HP and +16.5 lb-ft of torque with no ECU tune required. The custom NextGen enclosed airbox design shields the filter and incoming air from engine bay heat, ensuring a consistent supply of cool, dense air to the 5.0L V8 during daily driving, towing, and hauling.

Installation uses the factory mounting points and can be completed in 60 minutes or less with standard hand tools, with no cutting, drilling, or modifications required. The intake tube retains all factory EVAP and crankcase vent hose connections, maintaining full OBD2 compatibility on a stock tune. The pre-oiled cotton gauze filter requires service only every 100,000 miles. Proudly designed and manufactured in the USA, the 70-2591 is backed by K&N's No-Hassle Lifetime Limited Warranty and will not void the factory Ford vehicle warranty.
