Install them yourself and buy a tuner?
It's a suggestion but it may not be what you wanted.
I don't know any members off hand that have a tuner out in LA.
the stock thermostat runs at 195 degrees, the 160 is too cold, and the 180 doesn't drop the temperature that much. if your coolant system is running properly, then 15 degrees colder isn't going to make a lot of difference. plus, you have to tune for it so you don't get a check engine light.
