FA1778 Air Filter for Ford F250 F350 F450 F550 6.0L Powerstroke
FA1778 is a deep-pleat engine air filter, 330 mm wide and 267 mm long, built on a rigid plastic frame with a cellulose-blended paper element, replacing 3C3Z-9601-BA, 4C3Z-9601-AA, 3C3U-9601-BC, A2991C, CA9516 and AF26152. It fits Ford 6.0L V8 Powerstroke Super Duty F250 F350 F450 F550 2003-2007 and Excursion 2003-2005.

❓ FAQ
F250, F350, F450 and F550 Super Duty with the 6.0L V8 Powerstroke built 2003-2007, and the Excursion 6.0L from 2003-2005. All of them share the same airbox.
Yes. 3C3Z-9601-BA and 4C3Z-9601-AA are the Ford numbers for this element, and FA1778 is the Motorcraft catalogue number for the same panel.
No. This panel fits the factory airbox only. An aftermarket intake replaces the housing and takes a different element, usually a conical one.
330 mm wide and 267 mm long, with a rigid plastic frame. Published depth figures for this element range from 210 mm to 236 mm, so this page does not state a depth. Compare the new filter against the old one before fitting.
At 30,000 miles on road use. On trucks working gravel yards, farms or construction sites, inspect the pleats every 10,000 miles, because the dirt is packed into the folds rather than sitting loose on the surface.

Description
Product Overview
FA1778 is a deep-pleat engine air filter for the Ford 6.0L Powerstroke airbox, 330 mm wide and 267 mm long, with a rigid plastic frame around a cellulose-blended paper element. It replaces 3C3Z-9601-BA, 4C3Z-9601-AA, 3C3U-9601-BC, A2991C and CA9516 and covers Super Duty F250, F350, F450 and F550 pickups with the 6.0L V8 built 2003-2007, plus the Excursion 2003-2005. The frame holds the pleat pack square so the element seals against the lid gasket under boost. Replace it at 30,000 miles on road use.
