K&N Performance Intake Kit for 2008-2010 Ford F-250/F-350 Super Duty (6.4L) - 57-2576

Fits 2008-2010 Ford F-250 and F-350 Super Duty models (6.4L).

The K&N 57-2576 Performance Intake Kit is engineered to eliminate airflow restriction and provide a measurable increase in horsepower and torque. This system replaces the factory air box and intake tract with a custom-engineered, rotationally-molded high-density polyethylene (HDPE) tube. By increasing the volume and velocity of air reaching your engine, this kit improves throttle response and engine sound across the power band.

At the heart of this system is K&N’s signature oversized conical air filter, featuring washable oiled cotton media. This filter provides excellent filtration and can go up to 100,000 miles before requiring service under normal driving conditions. A custom heat shield is included to protect the intake air from high engine bay temperatures. The entire system is designed to bolt onto factory mounting points, typically allowing for installation in under 90 minutes with standard hand tools.
