With WIX and Purolator owned by Mann-Hummel, apparently a lot of the new stock of WIX (i.e., Carquest) are re-branded Mann filters. As seen with the oval holes that are seen in Mann filters.
A lot of people not happy with the Mann-Hummel new iterations of Wix filters, claiming - and sometimes showing - lowered build quality.
I found photos of NAPA Gold, a.k.a. WIX, a.k.a. Carquest Blue, of the same era of the old filter I just replaced. The nicely oversized holes have a slight rounded profile edge that was perfectly even around the hole. So the slightly uneven rounded edge holes on the old filter I took off suggests some wear.
