So I used this thread and bought a NAPA 1324 oil filter for my Kioti CK30 with 902 hours on it. Well it went on and seems to work but be warned, the NAPA filter is much taller than the OEM and sits within 1/4" of the side engine cover. And, oh the horror, it's white. Which is actually pretty nice so that I can write on it the date and hours on the machine for future reference.
