A little late to this party - but I had the same problem with an overtightened oil filter and took it back to the dealer to be removed - at which time they managed to hit my new Outback and scuff the rear bumper when parking another one too close. Never again!
 
Anyway, the problem is that the caplike filter sockets that you buy at Advance or Napa, metal or plastic, are 67 mm and very slightly too large - so they slip just enough on an overtightened filter to round off the edges of the filter flats. Those aftermarket sockets would be fine if the filter was not on with excessive torque. The OEM subaru oil filter socket is 66.5 mm and a more precise fit - at least for the old style made in Japan black filters (which I bought out a dealer's supply of about 5 dozen when subaru changed to the blue Honeywells - which I will not use).

"I use a metal cap nut that fits tightly over the end of the filter. It fits the many flats on the end of the filter so tightly that it cannot possibly slip. If a cap nut slips, it might not be the right size. I have two cap nuts for the three cars we presently have."
 
Now I find that my cap nut that fits the old black filters does not fit the new blue filters. The blue filters are slightly smaller in diameter, and I cannot find a cap nut small enough to fit them tightly. So I had to buy the gizmo with the clamping fingers.

I have two "gizmos with the clamping fingers" and they both are too big for the blue filters.
 
16.5" (4.25" jaw) channel locks for me.
