UPDATE - K&N 204
Several unnamed sources at undisclosed secure locations have passed some information on that may be of some use. I've seen no official information to back this up, so treat it as a 'advisory' only.
Some recent 'oil filter failures' have been attributed to a change in manufacturing location (China) and seem to be isolated to this particular model. If you are using this filter, check carefully that the O-ring is compressing when you tighten it down. There have been several instances where the filter is fully screwed on (bottoms out on the bung) before the O-ring has a chance to compress, resulting in O-ring 'blow out'. The mating plate is not dished as much as previous models. Be sure O-ring makes contact with the engine mating surface well before reaching torque.
I have been using the 204's on the R3 and have recommended them up to this point. I went out and checked my spares in the shop (stamped 'made in Korea') and they looked OK. So, if you have these - check to see if the top of the center threaded hole is no less than about 5 mm below the O-ring. Any less than that (or stamped made in China) - don't use it and return it if you can.
EDIT - another way to check that you have a 'good' 204 is to remove the O-ring and spin the filter on by hand - if it spins freely until metal on metal contact, you should be good. Take the filter back off and reinstall O-ring, then you should be OK.
And in the spirit of this forum, which is to try to provide 'good' information to folks that may not have much experience with these things, I'd offer that just because someone has used a non-recommended filters, oil, tires, etc. with no apparent problems does not mean that practice should be promoted or recommended on the forum. At this point I'm taking the position that the OEM is the filter that should be used.
