Since I hate waiting on parts, I went to the dealer and got a whole new thermostat housing even though it was a lot more than ordering one but not that much after shipping. I tried to look at and compare the new PN thermostat to the old one I had and I couldn't see any differences, they looked identical.

It did fix the issue and now my coolant temp goes to 190-205 even when cruising down the road at 40-50 mph.
