I recently replaced fuel filter on 2011 Czech-built 1.6 diesel. I still have the old filter, it is Hyundai part 31922-2R900, made in China by UFI.
I measured the inside diameter of the thread in the bottom of the filter and it is 8.6mm, so I guess the thread size is 10mm.
You can try
PartSouq Auto Parts Around the World and search using your vehicle VIN number. This will give you drawings of all the engine parts and the correct part number for your oil filter. If you then search for that part number you should be able to find equivalent filters from Mann, Bosch, etc. If you then go to their web-sites, they may have drawings of the parts which detail the thread size.
Or, if you can find the part number of the sensor from partsouq, you should be able to find an exact replacement.
