Overall pleased with this billet product. Looks really good matching my coolant filter housing. Clearly it’s well made, and I should never have to worry about replacing it again.

Thanks RiffRaff

Looks good won't rust doesn't leak what more can you ask for

What a compliment to my engine I rebuilt my 7.3 and tried to use the stock thermostat housing big mistake it leaked terribly I immediately ordered this housing and could not be happier it looks fits and functions 100% better than oem

Nice upgrade from the factory steel housing. No leaks and great fitment

Just got this and can’t wait to install it. I bought a cheap other brand aluminum housing before RiffRaff made one and I agree with the other comments. You can by other cheaper brands but will they last…no. I put mine on 2 years ago and it’s leaking. I cannot wait to install my new RiffRaff housing with original Ford thermostat. One thing I learned about these trucks buy quality or OEM components and you’ll be good to go. I only buy Ford or RiffRaff parts.

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.

Amazing quality, finish and functionality. I have ordered numerous items from Riffraff and they never fail to impress.

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.

Excellent
