Default 5.0 190 Thermostat

I have 85k on my stock 2012 5.0 and am looking to change the factory coolant before the winter as well as put a new thermostat in.

The OEM 180 thermostat br3z-8575-a is no longer avail it seems and it points to br3z-8575-d as the replacement now which is 190 despite some sites still showing a pic of the original 180. I know as I just ordered one and got a 190.

Aparantely the 190 is in the newer S550 5.0. Would there be any negative affects using the 190? I assume by the time its fully open it wont matter.

OEM's will sometimes update parts depending on the feedback they get from their shops or customers. 190 may be the new standard because it shows to improve emissions or gas mileage. Those would be the only two things I could see them updating that part for.
