I've used 3614 equivalent Napa Gold 1348 on a Kohler (no) Courage engine calling for the same Kohler # filter as posted HERE. I had no leaks and no issues using it. The biggest issue with using the auto app 3614 in place of the/an OPE filter is it's somewhat longer than the shorty 8172 so need to check space for the extra length. Where practicable (length) I'd 'always' choose the less expensive automotive application filter over the pricey OPE filter. As an aside currently running another 1348 on a JD Briggs engine which also calls for the shorter application, enough extra space.
