Your engine will run rich longer

Run rich longer? Most cold start and coolant maps I've seen stop compensating around 60 degrees, well before 82 degrees.

they look awfully simerlar to 4age ones.. TRD make a few different versions including a higher flowing version from memory

The dudes at the local parts place gave me an 82 degree thermostat that's apparanlty out of a Rav4

Fitted in fine, and haven't had any issues with it - temperature usually wanders between ~80 and ~90 depending on what the thermofans are doing
