The K&N 57-2573 Performance Air Intake System replaces the factory air filter and intake tube on 2006-2010 Ford Explorer models with the 4.6L V8 engine. This system uses a roto-molded high-density polyethylene tube to deliver more airflow for gains in horsepower and torque. Paired with a washable high-flow oiled cotton filter and custom heat shield it improves engine breathing while protecting against hot underhood air.
