Are sun visors of Golf 7 the same with sun visors of Yeti?

They are aproximately the same number...1KO 857 552 with 1Z0 857 552.

I founded some black sun visors for Golf 7..

No - if they were the same they'd have identical part numbers

 

 

Part numbers aren't random so you'll probably find most sunvisors have similar part numbers.

 

That's not to say they won't fit - but that's harder to know until someone tries.

 

I thought that the 1KO and 1ZO were the common prefixes for the different models but if the numeric part number was the same then the part was.

 

Although the latter I may have invented.
