Soooo much better than the original housing.
Definitely would buy again and worth the couple extra bucks. -

Quality
The quality of the product is evident as soon as you open the box. I have had 2 other covers from other companies on my other 7.3L and they don't compare to the quality of this one.

I ordered this Riff Raff billet thermostat housing for the new water pump I was installing. The original housing was rusty and needed to be replaced. Shipping was fast considering I live in Key Largo Florida. I know this will last me my lifetime and it looks good. Thank you Riff Raff for carrying original Motorcraft products and quality Riff Raff products.
Excellent customer service. -
Quality product
Had tried everything to fix my leak at the thermostat housing including a new parts store housing, still leaked, this seemed to do the trick, my only complaint is a new seal isn’t included.

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.

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!
