I just called Napa and Orielly asking for a 180 degree thermop and they said no listing at all or OEM or 180 degree.

What am I missing?? I am asking the wrong question?

 

Yup, wrong question.Don't ask specifically for aT-Stat for a Charger w/a 5.7, they will not find one.

You can get the T-Stat by size. It's 63mm or 2.5".

Ask NAPA for a "191 THM" T-Stat, if you tell them what it's for and they try to cross reference it then it's going to get deep and you'll wish you never brought it up.

At first when I got mine they couldn't find it. I looked at what the searched for and it was plain "191", I had to remind them to put the THMat the end of their search. They may not have it in stock but they should be able to get one within a day.

 

I will go buy today! Thanks Mango

How big of a difference does it make anywho???

 

Enough that you would notice it. If you haven't noticed your car runs much better on cold days. The T-stat will give similar results keeping the engine coolor and delaying heat soak.

IXLR8 said in another post that performance was better after taking the engine top hat off. That allowed more airflow and kept itcooler.
