SPE 6.7L Powerstroke Low Temp, High Flow Thermostat

Thanks for this product. The thermostat did exactly as advertised, however it did not lower engine temps on my 6.7. I could tell that it opened when it was supposed to and it took longer to build temp, but I still wound up running at 240 degrees plus pulling a trailer. I'm definitely leaving the SPE thermostat in there, but am exploring other options to get engine temps down a little. I would encourage you to explore other shipping options than USPS. It took too long and arrived 2 days later than original estimates. In today's economy. It shouldn't take 8 days from time of shipment for me to get it. I have zero confidence in the USPS. Otherwise, your service and communications were great! I'll continue to be a customer.

I have your guys fuel filter relocation, piping kit, full intake and now the thermostats. My truck empty was around 210*, loaded would get up to 240. 176 now unloaded and 185 loaded. Thank you guys for the great products

The low temp/high flow thermostat was easy to install. The hardest part was getting the clip back on the top radiator hose because of where it was located. Have only driven the truck about 5 miles since installing the thermostat but I can tell that the temperatures are lower.
