Same goes for driveline and fuel filter, doesn't need to be done.
Definitely use genuine coolant, designed for Subaru cooling system components.
I know your trying to save money, but genuine parts are always the best choice, some aftermarket oil filters have been known to leak because of the very high oil pressure in EJ engines at cold start.

And don't forget the upper engine cleaner (part no SA459) and fuel additive (part no SA718)
