Billet thermostat housing
Awesome looking part that really preforms beyond industries standards. Countersunk bolt heads, stainless steel hardware, and not to mention the color options. I went with blue and it really impressed. Customer service is on point and can answer any question you might have. Highly recommended.

Thermostat
Durable and looks great

Very Nice Quality
I bought a thermostat and housing from the big parts stores when I replaced my water pump and thermostat, also replaced the housing as recommended when doing that job. 2 weeks later it started leaking, fixed it by throwing a new gasket on and what do you know, 4 months later it was leaking again. This time I got the MOTORCRAFT thermostat which comes with the gasket pre-installed and THIS housing (Red) which matches my truck. It looks great, comes with new bolts and the best part...it doesnt leak anymore!

Stops leaks!
For not a lot more in cost over the stock thermostat housing, you can get this one that will eliminate leaks when used with a Motorcraft thermostat. I've installed these on two trucks now and the leaks are gone...
