Oil filters The oil system of Harley-Davidson changed between the Evolution and Twin Cam models. On Evolution models the oil filter system is in the return section and uses a 30 micron filter. On Twin Cam models the oil filter system is on the pressure side and uses a 10 micron filter. Oil filters can not be changed over!
