K&N 57-2541 Performance Air Intake System 1997-2004 Ford F-150 & Expedition, 1997-1999 Navigator

K&N 57-2541 Performance Air Intake System, Fits 1997-2004 Ford F-150, 1997-2002 Ford Expedition, 1997-1999 Lincoln Navigator

A high-density polyethylene (HDPE) rotationally-molded tube helps increase the volume of airflow to your engine, and provides a guaranteed increase in horsepower and torque. These systems are paired with a washable, reusable High-Flow Air Filter™ featuring oiled cotton filter media. The oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A custom heat shield helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 90 minutes. Some intakes are not legal for sale or use on any pollution controlled motor vehicle in California. See the product specifications for CARB status on each part for a specific vehicle. Certain 57-series intakes are designed to function with the factory air box, and feature a panel filter paired with a custom roto-molded intake tube.

K&N 57 Series kits are truly state-of-the-art.  We start with the largest conical shaped high-flow air filter we can fit into the engine compartment while using factory holes and mounting points.  This extra filter size provides even more airflow at lower restriction than a standard K&N O/E replacement filter that is limited to the size of the factory air box.  The oversized air filter also captures and holds more dirt increasing the service life before a cleaning is required (up to 100,000 miles).  When possible, the filter is isolated from high engine temperature by a heat shield designed to lower the temperature of the air entering the engine, which increases horsepower.  Next we attach the filter to a rotationally molded tube made from interlaced High Density Polyethylene (HDPE).  This process allows us to precisely shape the tube to reduce turbulence and accelerate airflow into the engine.  This is why some of our tubes have unique shapes that are specifically engineered for each application.  Finally the tube is connected to the engine with adapters made from high strength materials such as silicon and reinforced nylon and ensures long life.  Put all this together and you have the best high-flow intake system available today.

NOTE: Some FIPK's will not fit on vehicles with lift kits.
