Just to correct my first post, apparently McGeorge Toyota isn't selling these anymore, according to my bookmarked link. They are sought after by the Lotus crowd as the filter to use.
I have a carton of the Thailand ones also, they are original, not aftermarket. Both kinds are torque stopper. The Japanese ones have red o-ring and nylon cage, very nice finish on the baseplate and threads.
These pictured here look somewhat authentic on the paint job, maybe they are Toyota Asia. But they make Rolexes almost identical LOOKING also, it isn't hard to fake logos these days with computers. Original Toyota filters have a foil logo seal on the box now, like someone else asked, which shows how bad the pirating situation is in China.
