Description
Fits: 2003-2007 Ford F-250/F-350 Super Duty 6.0L Power Stroke diesel.
This application-specific AIRAID cad intake uses a serviceable filter and a vehicle-matched inlet arrangement. Its supplied panels or airbox manage the filter area without changing the truck into a different engine or emissions configuration.
Selected part: 400-131-1 — Red oiled / service filter 720-128; 401-131-1 — Red dry / service filter 721-128. Quantity: one selected kit or service package, not all options.
Included components
filter, cool-air box, intake adapter tube, top panel, 27.5-inch weatherstrip, hose mount, grommet, billet box mounts, gasket, fasteners and T20 bit
Installation and service
Retain the original turbo inlet hose, filter minder/grommet and correct IAT or MAF sensor; follow the early-2005 sensor-specific installation branch.
Service only with products appropriate to the selected media: oiled filters require cleaning, drying and controlled re-oiling; dry synthetic filters must not be oiled.
Emissions and application notes
Official CARB EO D-609-18 lists the selected part numbers for the stated application only. Follow its installation conditions and retain the factory emissions systems and calibration. This is not a universal road-legality claim; other applications and jurisdictions require separate verification.
The current manufacturer legacy 400-131-1 red-filter section, including the 2003, 2004, 2005, 2006 and 2007 F250 6.0L vehicle pages, specifies EO D-609-18. Do not substitute the California-restricted yellow-filter 404/405-131-1 revision. Exact MPN and application conditions govern; no universal road-legality claim is made.
