Upgrade the underhood appearance in your 2003-2007 Ford 6.0L Powerstroke with the XDP 6.0L Billet Fuel Filter Cap XD266. Built from billet aluminum, XDP’s Fuel Filter Cap replaces the factory cap that becomes damaged and brittle with age.
Note: This cap does NOT include an O-ring. It is recommended that this cap is replaced during a filter change as most filters will include a new O-ring.
