They make your car run cooler and it depends on what other mods you have on which you need... In most cases 180 is more than enough... if you don't have any other modifications don't bother with it.
 
well ive been doing normal things to it just getting it all up to date i put in autolite 606s gapped at .055 new wires oil filter tranny filter oil and flushing coolant now and changing thermostat and later this week im goiing to throw a cone on my throttle body and i was also wondering what i should get for this. Just one of those long spectre filters? and put the censor in the rubber? thanks in advance
 
well i plan on doing some mods to it but untill then will it do any harm running a 180 with just my intake done?
 


ok thanks guys so when do you suggest i do change the stock one out like when i start doing things like headers pcm and pully drops?
 


It helps reduce KR actually. Even though its just by one (usually or if that) it helps. Its the cheapest beneficial mod you can do.

Though in my opinion not needed until you get a couple more added on.

If you're in a warmer climate state like me, Texas, stick to 180. 160 will be hard on the car and will see a definite change in gas mileage.

leave a stock T-stat then. Specter works fine... K&N can sometimes screw up MAF sensors(the oils).

The K&N CAN mess it up if you don't properly maintain your car and filter. The MAF needs cleaned every so often. I've had one two years, and no issues at all. And keep the stock 195* thermostat, otherwise you will be wasting money for no reason on fuel. The 180* is a patch to help prevent KR, but you shouldn't rely on the t-stat to lower KR.
 
I've noticed that on the dyno you will make slightly more power with the coolant at 180 vs the coolant at 195. Like 2 or 3whp... it does a better job of removing heat from the heads when you're beating your car up, but if you don't race it a lot there's no real reason why you should get one.

I have a 180 on my car though... I'd never go 160.

it won't harm anything it may slightly hurt your gas mileage though.

In the summer, a 180* isn't so bad. In the winter, a lower thermostat will be harder on the engine. Keep it stock - don't change things just because you feel like it.

Lol well even so. Opinion is invalid for replying like a 13yr old teeny bopper :p


Thermostat upgrades will benefit or hurt depending on your climate.

For example: if you live in the northern states I'd imagine that this mod would not be helpful really do to the temperatures.

-I've seen this mod reduce kr. I agree, do NOT depend on this mod alone to reduce yours. But if your car isn't prone to KR then I wouldn't worry about it.

In other words its very circumstantial. Scan your car first.
