Why I installed a low temp thermostat.

You have to remember manufacturers run their engines hot to lower emissions, not enhance reliability.

Yes, with the caveat that everything is a tradeoff. Lower temps might mean better reliability but at the expense of increased emissions and shorter oil change intervals.

Yes. And, resellers sell things (different than factory) to make sales. With no evidence, empirical or anecdotal, that suggests that a quicker opening thermostat accomplishes anything - other than to get people who have a factory set up to purchase and install a cooler thermostat. As I've said above, I don't say cooler isn't possibly better but, in the absence of heat issues, there remains no compulsion to alter the factory set up to simply change out a thermostat.

Actually, there is substantial empirical (ranging from improved UoA’s, to even a pre and post install Dyno pull or two) to anecdotal (“improved fuel mileage”, “faster warm up in cold weather”) data available on this subject (ad nauseum), but that would require actually doing a search to understand why changing the thermostat is a positive, and in which models Porsche already uses them from the factory.

So, yes, these things actually work……………………..

I am planning on putting in the low temp thermostat in the next few weeks. Is there any difference in quality between the Wahler and the LN Engineering thermostat. The Wahler is about $100 less expensive and I could obviously use the money towards other parts that I would like to replace. Greatly appreciate any feedback.
