KCJeep has it pretty well covered here. Besides the silicone adbv, you got a more efficient rated filter than the MG, so yes the media is different. As he also noted, the only other difference 'could be' the type of thread end bypass design. If you see the same metal coil spring design at the thread end return opening of the MG, then there's no difference as compared to a Wix. If not then that application likely uses a nitrile combo valve. As for whether it's worth the difference, imo for a ~5k or less oci, probably not so much. Beyond that, the Wix becomes more cost effective.
To be clear though, other than the Napa Gold (same as Wix) any non branded/labeled Wix filter, is a Wix 'made for', to specs of the supplier/seller, not Wix. That is for the cellulose/blend type media filters.
And for a recap of the O'R MG filter manufacturers since 09, Purolator, Fram, briefly Champ (some ecore), and now Wix.
