160 is best for horse power....180 is what Mazda installs...195 is good for fuel economy....Got this out of Felix's Car FAQs... https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

I've never had great results with aftermarket thermostats, they seem to have different opening range but the same average of temperature as the genuine part. :dontgetit: So I've always got up and down temperature. ??? or it's just bad luck.

I've heard that most aftermarket thermostats open too slowly compared to stock.

So you've noticed the same instability with these thermostats? It's also true for other cars too. On my Chevyvan I've got that same instability of temperature until I put a stock one in it. When you hit the gas for too long you can see the temperature going up.

I always stick with the stock one.

14 freagin years I been buying thermostats, and never, I repeat never has the gasket come with the thermostat, and vise-versa : you could buy a gasket without a thermostat. So I take the thermo housing off my car, and go to get a gasket, guy gives me some **** chevy one that leaked ( I only started the car in the driveway, didnt drive it), I call my local Mazda dealer, and Im told it only comes WITH the thermostat as a kit. Thing that kills me is I just got parts from MazdaTrix, and was going to get a new thermostat while I had them on the phone, but didnt figuring mine was only like 2 years old. Oh well, serves me right for not just getting the damm thing in the first place.

I've heard the same thing. And your car is made to operate @ a certain temp, so changin that would be bad, I wouldn't use one on a street driven car.

That's probably true if we talking about aftermarket thermostat because if you have a 180 and you're asking for power, the temperature would climb to high, may be as much as 200. As for a road trip with a 180, it would run cold. I'm pretty sure since I've tried 2 of them and both the same results. https://www.nopistons.com/forums/pub...DIR#>/wink.png

Couldn't you just use some silicone?
