I had to punch 3 holes in the one that was on Scarlett so I could stick a BIG screwdriver in it to turn it, and even THEN it was a BEOTCH to get loose......Bertha's filter had a nut on the end.......SOOOO easy to remove.
I WAS going change all 3 fluids, but, the oil filter had me so pissed, I thought I better wait until tomorrow to finish the other 2.......
Thats why I use the K&N filters. I like the 17mm nut on the end ofthe filter. No special filter wrench is needed. Just a 17mm socket and a ratchet with an extension. No needto have to destroy the filter to get it off.
