oil filters

[Mr. Big Time]

Heres a link to a company that sells oilfilters for the ds. I havent came across any other companys that sell them yet other than factory. They are selling them in packs of 3 for 30$,

http://www.partsforatvs.com/canam/ds450parts/maintenance.asp

or bikemasters.com sells them individually

Scotts also sells the stainless filter for the DS450, then you do not need to buy filters again, just blow out and reuse.
