I used the one from the autoparts store it's the help! brand little packet things. It says dorman 495-004 chrysler. The number on the top is 42064. Fit in the hole in the mp valve cover. Maybe your hole was made too big?
Fram is just not constructed as well as many other brands, I used to use them before I looked into it. I figure why take a chance to save a couple bucks. Sometimes I use mobil1, purolater or k&n.
