Well, at $60 each they're extremely profitable...as are fuel line magnets, electronic rust protectors, and the Vornado.What I can't figure out is how someone can have so many posts in this thread yet not be able to relate anything particularly useful from their personal real world experience. Surely this personal real world experience contains hard data, from which objective decisions can be made. My personal real world experience involves wrenching on cars for over 15 years. It involves a 4-car garage full of tools and instruments. It involves a LOT of measurements. As I said, I know how long it takes for a thermostat to open. I've measured the decibel levels my car makes at every 1000 RPMs inside the cabin, with and without headers. I've measured the temperature profile of my cats at idle from a cold start. I've measured my coolant temperature at idle and after a spirited drive (after verifying the calibration of the temp sensor). I've measured my oil pressure throughout the powerband. I've measured my fuel pressure. I know how long it takes before my O2 sensors start to kick in. I know how many kV my coils generate. I know my cylinder compression. I've measured the size of each of my cam lobes. I know the temperature of my rotors after a single panic stop. On another car I know how much vacuum it takes to work the EGR valve. On that car as well I know how many amps a new fuel pump requires vs. one that has 120k on it. I measure the runout of all my rotors after every brake pad change. I even know how many watts most electrical things in my house consume. And believe me, I'll be spending many hours at work this year and next for qual testing things after they're built. Did you honestly go through this type of rigor in understanding cause and effects when changing thermostats?I'm more than theoretical, but theory is very important. If we only relied on experience imagine how many bridges and skyscrapers would collapse each year. If you want to disagree with theory, be prepared to back it up with useful info. Vendor marketing BS doesn't count.
