Well you must have had bad luck. I have used them exclusively and had no problem. The torque necessary to put them on is not very high.
Also this is the first I remember reading that they are failing. Maybe I just missed other such reports?
Google K&N oil filter leak. You will get hits for both cars and motorcycles.
K&N sources from China. They used to source from Wix and had no issues to speak of. Not any more it seems.
Suzuki buys from a manufacturer so they are not the OEM for oil filters.
Hi-Flo and Wix actually manufacture their products. I stick with them and have never had an issue.
