I got a "premium" CarQuest filter for now. They are apparently made by Wix and this one looks pretty good to me. It's certainly bigger than OEM, but will fit the Bandit fine.
Speaking of fitting, it looks like I'll have to remove the radiator hoses if I want to have enough room to remove the old thread, and there lies a problem. One of the bolts that hold the radiator hoses is rounded, so I can't remove it even with "sure-grip" socket :(. Couple that with my reluctance to throw away oil/filter after only 3,000Km and it looks like I might not be doing this mode very soon.
