The Xtended Guard is a good(well made) extended OCI filter from Fram, I'd have no problem using it.
My only reservation, as crazyoildude mentioned, is that sometimes non Motorcraft filters can exhibit a start up rattle in a Ford. I say this because my son has an 05 2V 4.6L that had it when not using a MC filter.
You could certainly try it, if no start up noise then great. If you get it then you could decide if/how much it bothers you, then swap it out. But the XG ( believe it) is a solid filter from Fram.
