Mann are also made in Korea, supposedly at the same factory where Kia/Hyundai filters are made by Mann. Not to confuse with YoungDong made oil filters - they are the ones with phone number 031)339-2507 printed on them.
Wix has been reboxing them now, too, being they're under the Mann umbrella now. Plenty of Wix 51334, Napa Gold 1334, and even the Proselect 21334 cut open on BITOG and they were all reboxed OEM/Mann
