From my perspective, the only thing that matters is the pressure the oil pump generates. For our scoot, it is identical to cars. Any car Filter will work. It could be different for other bikes. How many raiders are very happy with the K&N303 or 204? M1-110 and M1 108 relate to 303 and 204. The latter is shorter. I'm very happy with the M1-110.
