The K&N 57-2575 Performance Air Intake System replaces your factory air filter and intake tube on 2007-2010 Ford Expedition, 2009-2010 Ford F-150, and 2007-2010 Lincoln Navigator models with 5.4L V8 engines. This system uses a high-density polyethylene roto-molded tube to deliver more airflow for a dyno-proven gain of 12.3 horsepower at 5400 RPM and added torque. Paired with a washable high-flow oiled cotton filter and custom heat shield, it improves engine performance while protecting against underhood heat.
Key Features
- Oversized high-flow air filter: Washable and reusable oiled cotton media lasts up to 100000 miles between cleanings under normal highway driving.
- Easy bolt-on design: Replaces OEM components without cutting or permanent modifications.
- Custom heat shield: Blocks hot engine bay air to maintain cooler denser intake charge for consistent performance.
- Direct bolt-on fit with no vehicle modifications or tuning required.
- Filter cleaning required every 100000 miles under normal highway conditions using K&N cleaning kit.
- System maintains factory intake sound levels while adding subtle induction growl under acceleration.
