Before you go and buy the t-stat, think about why you want to install this. If you don't know why, then do some research and find out the benefits and downsides to the mods.

Personally, I am running a stock 195° stat right now because I am most concerned with fuel mileage. I have found that a 180° stat in a daily driver will cause me lower fuel mileage. I do convert over to a 180° stat when at the track. But for everyday use, I keep a stock stat in it.
