160 or 180 will just let the coolant go throgh the block faster keeping it cooler so basiclly your moter will cooler.

I live in FL and 160 was still too cold... 180 is the best for these mod motors, well unless you want to get a tune just to run a 160 thermostat... it isn't worth it in my opinion just save all the hassle and use 180.

I agree that it wont give any more power. I changed mine because it was cheap and I was already in there!

Leave it stock....
The OBD2 system has rendered that mod mostly useless.
However if you insist, a 180 probably won't cause any problems but a 160 will throw codes almost for sure.

Personally, the cooling system on the 4.6 is a cantankerous beast and can be very difficult to bleed air out of so I tend to leave it alone except for the yearly flush and fill.
The last thing you need in one of these motors is hot pockets of air.
