Hey Numbers, I don't understand why you need a filter wrench to change it, unless you can't get your hand in there to get a good grip on it, ALL my filters, car's, mower's etc. all spin-off by hand, ... I hand tighten them ON ( lightly oiled on the gasket ) until it makes contact, then APPROX another 3/4 or more turn, it just has to seat SNUGLY, .... NO eating the WHEATIES before-hand !! ..:thumbsup:..:laughing:
