RCPILOT82:
I don't know where you got your info on the PH10590 as being correct. The Fram website only says it's compatible with Chrysler products.
I thought the PH10575 was incorrect at first too. As I stated in an earlier post, I bought a used 2011 LT with a PF-48 installed. I had bought a PH10575 but couldn't seem to thread it on. So I went out and bought a PH10060. It went on, but not real easily. Next time, I was prepared with both; the 10575 went right on. I've since put a 2nd 10575 on.
Looking at Fram's technical info, the 10590 and the 10575 appear identical, except the 10590 is almost an inch longer:
