Product Description

The K&N 77-2591KP High-Flow Intake Kit is engineered for the 5.0 L V8 engine in the Ford F-150 (model years 2015 through 2020). It replaces the stock intake tube and air filter assembly with a high-flow mandrel-bent aluminum tube and a large reusable cotton gauze filter, enabling improved engine breathing, enhanced throttle response, and measurable performance gains of approximately 13.8 horsepower and 15 lb-ft of torque under ideal conditions.

Installation is usually straightforward and can be completed in under 90 minutes using basic hand tools. Because the system retains the factory mass-air sensor location and uses the existing mounting points, no tuning is required for stock engine setups. The washable and reusable filter reduces long-term maintenance cost by eliminating repeated disposable filter replacements. This kit is ideal for F-150 owners seeking an easy yet impactful upgrade to airflow, sound and under-hood aesthetics.

This intake kit is designed for the 2015-2020 Ford F-150 5.0 L V8. Fitment is confirmed through 2020; coverage for 2021-2025 is unconfirmed at the time of listing. Always verify your vehicle's exact year, engine, drivetrain and regional emissions compliance before purchase.
