Location of the oil filter on a 300 ex?

Richard b is right. i would add that when you change it always make sure that the new oil filter has the rubber o ring facing out and the spring is behind the oil filter. if the filter is put in backward it will destroy your cam. as well as other parts.Location of the oil filter on a 300 ex?
Right hand side sitting on it. Cover has three 8mm bolts in it. Kind of round with the bolts on the outer diameter.
