I have a 2010 sportsman 550xp. I'm getting ready to 1st oil change on it. I went to my dealer and bought the oil change kit. The oil filter in the kit has 2520799 as the part #. I took the new filter to the local parts store and bought a wrench to fit it. When I got home and checked the wrench to the filter on atv, the wrench is too small. I called my dealer and he said that the new filter is the correct one. I did some checking online and my new filter has the correct part #. My question is this, should there be a difference in the size of the filter that came from the factory and the new one that I bought?
