 Saves me lots of money on filters but would have been better with a foam prefilter as its on my mower and gets clogged by grass daily.

 I have always had great results with your filters.

 I recently purchased a K and N filter for my 1974 wheelhorse c120 with an old Koher k301 cast iron engine on it, that I use for mowing, snow plowing and snow blowing in the winter. I got sick of paying out the nose each and every year for the OEM Kohler filters. So I installed my new K and N before mowing this past time. OH MY GOD. LOW END LIKE CRAZY. Like it never had before. Seems like once the governor kicks in it just PULLS through. Keeps the Rpms higher underload and overall it is just amazing that an air filter can do this to performance. Will I buy other K and N products absolutly. I am a small engine tech here in PA, I believe in keeping this older equipment running as long as possible and then some. I have a 3 other wheelhorses ranging in dates from the late 70-s to late 80s and a massy ferguson garden tractor that will definitely be getting a k and N  when the time comes. Another thing I noticed is it does not get near as dirty as my old oem filters with the old foam pre cleaners on them. Awsome product , and its awsome that you guys made it for such an old tractor like mine. Everyone wants the new cheapie stuff they sell at lowes and home depot, NOPE not me I like the good old garden tractors with so much torque they could climb a wall. I will defenetly be installing your filters on all my overhauls from now on no questions asked. Why throw money away in todays day and age?
