Crap filter quality really stinks now days. I had someone in my garage mocking my K-mart oil filters. I bought a case of filters back in high school 30 years ago and misplaced about half dozen filters. Finally found them in a box of old parts. I don't know who made them, but said made in the USA and look to be as good as a WIX when I cut last one apart. I hope 500ciBee finds the problem.
