It's a 3/4X16 thread. You could use many as long as the gasket seals and the bypass psi is right. My Ranger could use the same filter as your van. And I use a filter that is the same size as a Wix 51773. Mine calls for a FL1-A which could also work for you. The 4670 you talked about can work too. Btw, the The CAT filter I use is a 1.5 quart. Try the Baldwin website and punch in some filter numbers. It gives specs and you can compare them to Purolator.

I used a FL1-A on my 2003 voyager van, but the can diameter is larger than the 4670 (even though the thread size is the same) so I can't see how the FL1-A would seal on the 2009 Dodge van. Is the engine sealing plate the same on both?
Assuming the oil filter mount is the same as before (and I would be amazed if it wasn't), it will work fine. I have used an oversized filter on all Chrysler engines I have wrenched on (most have called for a PH16/FL-400 since the early 70's), it works, no problem. A few vehicles cannot, simply due to packaging.
