Same 22x1.5 threads as the PH2/FL820 used on a lot of Fords.
I use PF48 & Wix 57060 on my Jeep Patriot 2.4L engine which has a 4.5L sump, and I'm quite happy with them.
With Wix anyways, the 57060 has a better Beta then the larger 51372, so you might be getting a bigger filter, but it may have lower efficiency. Bigger isn't always better.
