I have two selections of oil filters for Buell owners. The first is the HiFloFiltro brand. Made in Taiwan to industrial spec, these oil filters exceed OEM specifications for filtration, and are fast becoming the #1 motorcycle oil filter in the world. The second option is the more expensive K&N brand oil filter, known for the large nut welded to the bottom of the filter. This nut makes it a cinch to install and remove the filter with a wrench or socket. Filtration of both filters is comparable in terms of performance.
NOTE1: When tightening oil filter, only do so by hand. Do NOT torque oil filter or it will seize. Oil filters tighten over time. Hand tight only.
