Every aftermarket parts supplier does after market oil filters.
Usually it is the same filter from the same factory with a different name on the outside.
Consider that at the worst you replace it once a season, the cost of the filter is a touch on the insignificant side.
I do find the resistance to to fitting a low cost necessary item like an oil filter they they happily fork out more than 3 times the cost of the filer to fit un-necessary fully synthetic oil.
