I'm ordering the hughes plenum kit and was going to get a new thermostat. I can't figure out which is better for my 99 2500. I use it light other than plowing in the winter. Any insight on these? Thanks

 

Easy. If it's a factory tune, go for the factory 195.

If it's tuned for a 180, then go for the 180.

Don't stick a 180 in there if you're on a factory tune. No reason to.

 

Since it gets pretty cold up there in New England, I'd go with the 195. I run a 180 with a stock tune here in central VA and the motor runs perfectly.

 

Ok thanks guys. Just ordered the kit and thermo. Il be slowly tearing the truck down till the kit gets here. Hope I don't run into any problems!

 

I'd stick with the 195 t-stat. Hope with some luck thrown in is good.

 

Well got the intake off in less than 2 hrs which surprised me. Only broke 2 bolts so that's what il be doing till the kit comes in. It was surprisingly easy, let's just hope I put it all back together correctly : )

 

When I ordered my kit a few years back I bought a 180 temp truck ran really rich burned up a lot more fuel cause truck computer thought it was cold i guess? So I put a new 195 in and it's been perfect I wouldn't get a 180 unless you got a tuner

 

Very easy just take your time I didn't it in my shop in about 6 hours

 

 

diy/faq poll says a 180 is best and it is. pics of the plenum fix?
