K&N 2015-2016 Ford Expedition/15-16 Lincoln Navigator 3.5L V6 F/I Performance Intake Kit

If you're looking to get more out of your 2015-2017 Ford Expedition or 2015-2017 Lincoln Navigator's 3.5L V6 engine, this K&N performance intake kit is designed to help. It works by increasing the volume of airflow reaching your engine, which can lead to a noticeable boost in both horsepower and torque. This kit replaces your restrictive factory airbox with a well-built system that's engineered to breathe easier.

The core of this system is a high-density polyethylene (HDPE) tube, rotationally molded for a smooth interior that helps air move freely. It's paired with K&N's signature washable and reusable High-Flow Air Filter, which uses oiled cotton media to capture dirt while allowing maximum airflow. The oversized, conical shape of the filter is designed to go up to 100,000 miles between cleanings under normal driving conditions. A custom heat shield is included to block hot air from the engine bay, ensuring your engine gets cooler, denser air for better performance. K&N backs this system with their Million Mile Limited Warranty.

Installation is typically straightforward and can often be completed in under an hour with basic hand tools, making it a practical upgrade for many DIYers. This kit is designed as a direct replacement for your stock air intake system.
