Extend Protection Plan

Fits perfectly and keeps the coolant temp lower just like it is advertised.

my temps after new turbo and mods skyrocketed in the Texas heat. now they are in the safe zone. Thank you SPE

Awesome Products , super fast shipping !!! Best in the business

This thermostat is an upgrade I should have done sooner. My 17 f350 Powerstroke runs so much cooler, coolant, trans and motor oil I’m still in awe.

Install took 15 minutes. Very easy and straightforward. Looking forward to adding more SPE components!

Great product, great communication and fast shipping.

Very simple to change and temps are 10-15* cooler

Fuel return valve installed very easily. A very quality piece of equipment. I’m impressed with the machine work and ease to install it.

The shipping was prompt and installation was quick. The thermostat performs as described. I’ll advise further after I tow my travel trailer. I’m currently in Silverton, CO in the San Juans. Altitude here is ~9,318’ . This will be interesting as our route requires crossing five 10,000’ passes. Including Wolf Creek see c w mc all’s song. This is the reason for the thermostat as the transmission temperatures rise into the mid to high 220f. Tlr weighs ~10,900 dry.

Great service

Easy to install

By far the easiest part I have ever put on my truck. The way the hose is molded it fits perfectly without any trouble. So far SPE has been a great company to buy from. Great communication from the time of purchase. Thanks for all the help!!
