As expected another great piece of machining from Riffraff. I had to replace my water pump and already had the billet inlet and that is a great piece so I knew this would be just as good.

I recommend this product for the ease of use. The oem steel outlet had rusted and I almost had to cut the hose off. The top hose I was able to twist off because I already had the billet inlet.

They look great and work even better.!

I was replacing the water pump on my truck and the original thermostat housing and straight lower inlet had seen better days 149k miles ago. They were rusty and crusty. I had ordered from Riff Raff before so ordering their billet thermostat housing and billet lower straight inlet was the plan when replacing the pump. Thank you Riff Raff for carrying Motorcraft products and quality Riff Raff products. Also excellent customer service when I have questions.
Thank you.

definitely the buy and worth it, looks great and more durable than stock.

These are the best deal going! Stronger and thicker than stock, won't rust and look amazing. Best of all they are cheaper than the factory motorcraft replacement part.

This thing is really robust, and including the motorcraft oring and stainless hardware is a very nice touch. Best of all it was less expensive than the Ford part. Really a no-brainer to upgrade.

This is a great idea, and I used it on my 1990 to upgrade from the rusted elbow to this billet anodized inlet and the later model radiator hose.

I have seen billet thermostat housings for years but this is great that someone has finally made a lower neck. Nice tight fit, stainless hardware, cant ask for more.

Out with the old rusty housing, in with the new beautiful part.

This is an awesome solution to the stock steel piece. No more rust, and leaks. Worked great on my 2003 7.3 when I installed the water pump, hoses and thermostat.
