Have always used K&N oil filters on both my Beta and Triumph. Really like the wrench-off nut on the Triumph can filter. Wonder if you have ever tried to invert the nut into the can to get a more flush cross section. As it is the nut is a bit below the bottom of the frame (on Triumph) making one take caution in lifting the bike for chain care.

Ordered this with free shipping, got it sent direct to my technician. Arrived very quickly, quicker than expected in all honesty along with a couple of free stickers Fits perfectly to my Triumph America, no leaks or mess.

Perfect fit for a Triumph Bonneville T100 and the chrome finish looks awesome with all the other chrome on the bike.
