Here's a cross reference site I came across that is pretty handy. I'm sure quite a few of you know about it. It's from the Fram website, but once you figure it out, you can see how to cross-reference other filters. You can do a "application look-up" to find a Fram filter, and use it to CR to other filters. Or, to the left side, you can type in, say an AC Delco filter #, and it will give you the Fram #, to which you can get the CR's.
