My factory filter was tight but not as tight as yours. I was able to get it off with my filter wrench but it took enough gripping and turning to cause a sore shoulder and wrist. Not the easiest thing to do while squeezed in a small space on your back. I didn't want to use my ramps because I didn't think I'd be able to drain all the oil out. How much oil did you end up putting in it? I was able to load 6.5 qtz and it was at the full mark perfectly.
