Thanks Joe, What he has is not the same one I took off my tractor. The one I originally had was 9 1/2 inches long and the fins were oriented in the other direction and all Japanese writing without recognizable numbers. I could not find an exact replacement for it around here but read that someone on the web is offering them for $60. Well, I'm not paying that so I went out and bought a fram CAK530 for $8.55 ,which is the exact same thing that dealer is selling on eBay for $30. It has the same 100CFM flow that the original had it's just shorter, so I made an adapter for it and now the filters are easy and $ reasonable $ to get.
