Better than OEM
My steel OEM housing had been leaking for years. This fit a 2001 F350 7.3l. I had to buy different cap screws than the ones supplied with this housing the water pump on my truck did not have fine thread. None-the-less, no more puddle of antifreeze under my truck in the mornings.

Excellent T-stat housing
$50 well spent and got rid of the leak caused by the flimsy, thin stock housing. This billet T-stat housing and Motorcraft F6TZ8575EA T-stat assembly work great together. Looks great too...

So many cool colors to choose from. Love the green, great job giving us so many choices. It's a great quality product.

Stopped the Leak!
Finally stopped my leak. I ordered a off-brand one from amazon because it was cheap. Would not seal no matter what I did. Gave up ordered one from Riffraff and a thermostat, fixed the leak and way better looking part.
