Urgent Question; MAF

Will this fit my car?

The one in my car:

Another one:

This one is a used item, part number is exactly as in my car.

Which one would you suggest? New is kind of strange for me, too cheap.

Bought the used one, as the new is only found in cars with M52 engine (as per realoem). Might still fit M50, not sure.
