I paid $22.99 for it back prolly 2 years ago or more now. But that was before shipping. I can't remember where I got it, but I waited till I wanted other stuff too, so the shipping was really a non factor.

I can't remember, but my neighbor got one at NAPA I think, and paid like $9 for the thing. It's not all stainless and no lifetime warranty, but he's had it longer than I've had my Jet, and no problems yet.

 

Just don't go lower than a 180*. Your engine needs to reach at least 170* for proper engine performance and so all moisture that has settled in the crankcase case be dissapated away. Running no t-stat or lower t-stat can prevent the moisture from evaporating resulting in bearing and other failures.

180* is a good number. The Factory uses higher one's for emissions control and all that crap. And yes you must use them in conhunction with one another or it won't do squat for ya. If you don't go wthe E-fan route, you'll need a programmer to adjust the on/off temps of the stock fan in comparison with the t-stat you use.
