Sup guys, I used the search item, but i want some responses. I live in southern cali. Temps are not cold or hot here. Kinda warm. So when my oem thermostat is rated at 180. If I want to lower it to 170, will it mess up my emissions; CAT? I heard somewhere that hotter is better because more fuel will combust. Is this true? What if I replace my thermostat with a 170. Will it screw it up. And what's a good brand of thermostat too? Thanks guys.

 

Just keep the OEM. You'll be hard prest to find any thing better. Plus it would be pointles.

 

OK. what would you suggest to be a good brand? OEM Honda or parts from autozone ok?

 

NO!!!!!! honda only autozone thermo s, nawww go wit the factory

 

I have a napa thermo and it works great...honda is usually going to be better but autozone or napa or advance is going to work just as good
