Information

The AIRAID 401-231 fits some Ford Expedition, Ford F150, Ford F150 SVT Raptor, and Lincoln Navigator models. See vehicle applications for details.
The AIRAID Cold Air Dam (CAD) Air Intake is engineered to give your engine larger amounts of cooler air to produce more horsepower and torque. The intake system retains the original location of the air filter but delivers a big boost with the addition of a huge open-element air inlet protected by Cold Air Dam panels that help to provide a steady, free-flowing supply of cooler outside air into your engine. The panels mount in the factory air box location and utilize any factory cold air inlet ducts that are present, while adding additional cold air passages to the filter. The panels also keep the filter isolated from the hot engine compartment air by sealing to the underside of the hood via blade-style weather stripping. This CAD system utilizes a replacement low-restriction intake tube. The 360-degree conical AIRAID premium air filter is washable and reusable, less restrictive than traditional paper, and assures superior filtration. The AIRAID Cold Air Dam Air Intake is easy to install with common hand tools. Some AIRAID air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

November 19, 2018 - Part 401-231
I have a picture I tried to attach is too large of a file. Maybe air raid can adjust the file size limits. But, overall the install was very easy schematically speaking. But actually doing it what stuff simple because the pipe was so snug that in order to put it together on the air intake and the heat block I had to use oil and elbow grease. And I'm a big boy that works with my hands every day. The clamps need to be bigger they barely reach when put on. At most you will get one and a half to two rotations from it being completely off. But the performance is noticeable. I like the extra ground and the extra get-up. It pairs nicely with my flowmaster 44 series exhaust as well. -F150 King Ranch 2009
