trettig 0 #1 Posted December 13, 2010 I am looking for an air filter (oil bath or air filter) for the Kohler k91. The motor is going into my Wheel Horse RJ58. Any suggestions. I would prefer to find an oil bath air filter. Would any air filter from the k series work? Tom Share this post Link to post Share on other sites
Kelly 1,028 #2 Posted December 13, 2010 Finding oil bath filter that is correct for your RJ will set you back $100+ a paper filter air cleaner will fit from a 4, 6, 7hp kohler, that will be your best bet. Share this post Link to post Share on other sites
