About this part

Product Details

K&N Engineering is well-known for making performance air filters and intake systems that help engines breathe better. This specific kit, the 77-2591KP, is built for the 2015-2020 Ford F-150 with the 5.0L V8 engine. It's designed to replace your factory air intake system, allowing your engine to take in more air, which can lead to a noticeable improvement in both horsepower and torque.

The intake tube itself is made from mandrel-bent aluminum, which means it has smooth, consistent bends for unrestricted airflow. It comes with K&N's signature washable and reusable High-Flow Air Filter, which uses oiled cotton media. This filter is designed to let a lot of air through while still trapping dirt effectively, and you can go up to 100,000 miles between cleanings under normal highway driving. A custom heat shield is included to help block hot air from the engine bay, ensuring your engine gets cooler, denser air. Installation is typically straightforward and can often be done in under 90 minutes.

This intake system is backed by K&N's Million Mile Limited Warranty, and it's designed to fit right without voiding your vehicle's factory warranty. Please note that some K&N intake systems may not be legal for sale or use on pollution-controlled vehicles in California; check the product specifications for CARB status for your specific vehicle.
