If anyone needs a new oil filter for there Baja Wilderness 250 you can get one from Yamaha 1UY-13440-02-00, Wix 57935, Napa FIL 7935. You will need an Yamaha O-Ring to go with the Yamaha Filter #93210-54175-00. Not sure if the o-rings that come with the Napa & Wix filters will work, I haven't seen them, just cross matched.

These filters are pleated not a flat screen like OEM. Much better!

PS. Wix makes Napa's filters and is a very high quality filter.
