Hey, I need to replace some more COP's on my 4.6L and was wondering if you guys would recommend the ones NAPA sells. The brand is "Wells" not sure of the part number, and keep in mind that my Mustang GT is a daily driver at this point so all out performance is not an issue. I just want a reliable COP that isn't going to die on me and cause my car to misfire occasionally. It's running fine right now, but I can feel another coil going bad. When that shop fixed it last month they only replaced two of the eight COP's, so the problem seems to be that the other COP's which are stock motorcraft and are 7 years old it seems they are dying sytematically. It has new Autolites in it now, but I also figured it would be a good idea to change them out with some brand new motorcrafts, and to give me peace of mind. So, back to the point, whats the verdict on these "Wells" brand COP's? Also, money IS an issue, hence the questions about these more affordable COP's.
