These washers are only a few thousandths smaller (ring diameter) than OEM Hyundai but I decided to try them anyway. I've used some of these on our 2018 Elantra and haven't noticed a leak yet. They shred very well and form an excellent seal that is maintained throughout the oil change period. No complaints and a much cheaper price than OEM.
