A lot of people think it helps a lot in performance. I would tend to disagree with that, but can't prove it. The car always feels faster if you think what you did make it faster. I went with a 160* in my truck because when I'm offroading it's not uncommon for the engine to be under full load and the vehicle barely moving. In that scenario, a lower temp thermostat gives you just a bit more room to spin the wheels before you get too hot. I'm sure the radiator isn't plugged too because pulling a trailer going 75 with the A/C on it stays right on 160*. Just a matter of the fan not being able to pull enough air for the big V8.

I would have to disagree about the radiator being a consumable. I have the original radiator in my '86 truck and it just started leaking a little bit around the side tanks last year. The coolant (green) should be flushed every two years. Dex-cool they say can go a bit longer, but I say Dex-cool can be immediately replaced with non-silicated green coolant.
