Magnum Flow Performance Air Filter from Advanced Flow Engineering is designed to improve
the airflow over the stock filter in a 2004 Ford F-150 with the Triton 5.4-liter V-8. The
filter utilizes medical-grade cotton gauze and deep open pleats to allow more air to flow
to the engine, resulting in increased horsepower, greater torque and improved throttle
response, according to the manufacturer. The Magnum Flow features 100-percent polyurethane
construction and incorporates washable, reusable filter media.
