Thanks for the help and info. I do not think I will mess with it right now. The reason why I was asking is, a couple of auto part stores are running sales on Wix filters. I bought 4 oil filters today for the price of, or a little less, then 2. My truck, 2003 Dodge 1500 4x4 Hemi, takes the same oil filters as her Jeep does so I was stocking up. I was just thinking about what else I can replaces that is easy to get to. I need to check her air filter and will probably replace it also.
