Yep, the Gen 1 diesels use a cartridge-style oil filter and the AC/Delco one does come in a white box. Wix sells one for the diesel too but it’s in the traditional Wix branded box.
Wow, very interesting. So GM used both Hengst and UFI filter housings on the 1.4L?http://www.wixfilters.com/assets/techBulletins/Wix/GM%201.4L%20Oil%20Filter%20Product%20Alert%20%20English.pdf
I think Wix has an article on this too, I seems there is two models of filter depends on the Hengst or not. The "normal" filter is 57674 for the none UFI cap according to RockAuto.
Here is the article, I think this answers the OP's Question.
You’re correct, for 2014 models WIX only shows 567674 for the gassers (both 1.4L and 1.8L).I found this when researching the Wix filter specs, from the way I understand the article this is only for the 1.4L. Does the 2.0 use the same still housing and cap? I would think it would be tough to install the wrong one.
FYI my car was built 03/11 and the 57674 is the only Wix filter that RockAuto shows that works with the 2011, so I wonder if the variations could come from the model of the vehicle since a few are listed in the bottom right.
