      Part No. 21-9124DS

      Warranty Details (LIMITED LIFETIME REPLACEMENT)

      The AEM 21-9124DS Brute Force HD Diesel Air Intake System produces horsepower and torque gains for diesel engines by replacing the vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Ford F250, F350, F450, F550 Super Duty models. Air enters the system through an extra-large AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located in the original air box with a replacement AEM embossed lid which is designed to protect the filter from engine bay heat and increase horsepower. The intake tubing is an aerodynamically engineered and highly durable polyethylene tube. This air intake system was developed to accommodate the engine's factory emissions control devices including the mass air flow sensor. The oval cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal. View the 21-9124DS vehicle applications to determine the legal status for each vehicle.
