Quality Part, Fair Price
Quality billet part. Installed very easily. Replaced my thermostat with the one set to 203 degrees and my engine is much happier in the cold temps.
Great product, fair price, and far superior to the OEM housing. -

Necessary upgrade
Replace your weak, warped, and leaking stock thermostat housing. This billet housing is a perfect fit that will last. Be sure to get the Motorcraft thermostat also, paired together it will be leak free.

03' Thermostat housing
Great look and easy install. 20 yr old one was definitely rusty and needed to go. Keep it up Riff Raff!

USA Made
It is a great thing to be able to purchase from a company the prides itself on USA Made parts. Fit was perfect, no leaks and the machining is excellent.
