I googled the filter for a 2009 Husqvarna SM 610 and the only part I could find is KN-154? Appears to be the only filter available? Kinda' weird, but doesn't matter, so long as it fits a 2009 Husqvarna SM 610. Anyone know for sure if the KN-154 is the correct filter?
I use the Hiflo HF-563. Might be the same as above though. Have been changing oil at approximately 1500 miles.
