K&N 97-02 Ford F Series V8-4.6L/5.4L Performance Intake Kit

K&N Engineering is well-known for its performance air filters and intake systems that help engines breathe better. This specific kit, part number 57-2514-4, is designed for 1997-2002 Ford Expedition models with the V8-4.6L or 5.4L engine. It aims to improve airflow into your engine, which can lead to a noticeable increase in both horsepower and torque.

The system features a high-density polyethylene (HDPE) tube that's rotationally molded to help increase the volume of air reaching your engine. It comes with K&N's washable and reusable High-Flow Air Filter, which uses oiled cotton media. This oversized, conical filter is designed to go up to 100,000 miles between cleanings under normal highway driving conditions. A custom heat shield is included to help block hot air from the engine bay, ensuring cooler, denser air enters the intake. K&N guarantees this system will increase horsepower and torque.

Installation is typically straightforward and can often be completed in under 60 minutes. This intake system is protected by K&N's Million Mile Limited Warranty, and it will not void your vehicle's warranty. Please note that some K&N intake systems are not legal for sale or use on pollution-controlled motor vehicles in California; check the product specifications for the CARB status for your specific vehicle.
