Half sized oil filter???

Ok, Here's a couple of pics of one next to the common 'short' filter. I really don't know what application these were for as they weren't what I had intended to order. The parts guy evidently wasn't familiar with turbo 2.2 engines as these filters certainly weren't the ones commonly used. They were a lot more expensive, also. List price was $13.35 and cost was $8.80 each. The paper tag with the handwritten part number is the only identification I could see.
It would be interesting to see if that part number will cross to some common brand filter.

That appears to be the same as the 51131 from WIX or 1131 NAPA
