Ok guys so tis the time to start getting my skis ready for riding this season. Even more so since the weather up here is the chicaoland area has been warmer then usuall. So my question is about oil filters. I just want peoples opinion on which one. Should i go with the factory one or is anyone out there running aftermarket ones? I know K&N makes a filter for our skis but does anyone else and is anyone running aftermarket ones or is everyone running the factory oil filter? Any and all input will be appreciated
