K&N 97-04 Ford F150/Expedition / Lincoln Navigator V8-4.6/5.4L Performance Intake Kit

This K&N performance intake kit includes the high-density polyethylene (HDPE) intake tube, a washable and reusable High-Flow Air Filter with oiled cotton media, and a custom heat shield. It's designed to replace your truck's restrictive factory air intake system, allowing more air into the engine for improved performance. The oversized, conical filter design is a key part of the system, and K&N states it can go up to 100,000 miles between services under normal highway driving conditions.

The rotationally-molded HDPE tube is built to help increase the volume of airflow to your engine, and K&N guarantees this system will provide an increase in horsepower and torque. A custom heat shield is included to help keep the intake air away from the hot engine bay temperatures, which is crucial for maintaining cooler, denser air for combustion. This entire system can typically be installed in under an hour, making it a straightforward upgrade for your V8-powered Ford or Lincoln.

This K&N intake system is protected by K&N's Million Mile Limited Warranty and will not void your vehicle's factory 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.
