Awesome Plenums
I bought these for my 7.3, and the fitment is great. One thing to take inconsideration though is the thickness compared to stock one. I am running a regulated return that feeds through the rear test ports of the heads, and because of the thickness difference I had to add a nipple to raise the AN fitting up a little. Not a big deal, and really like these plenums!

New Design
I ordered these before I knew they were redesigned. They are very nicely machined, and the anodizing is very crisp. I have not had a chance to actually mount them up (motor is out being rebuilt), however visually they are beautiful. I also opted to ask Clay about custom color (orange) which came out awesome.

Worked perfectly
Very sturdy design. The o-ring is handy because RTV is messy and can be a chore to redo.

Incredible
Read the rest of these reviews, they are all saying the same thing. These things fit great, are machined really well, and no more RTV.

Amazing Quality!!
You have to have these in your hand to really appreciate the time and engineering they have put into them. Comparing them to the stock, flimsy , restrictive plenums I can now tell why they are so much better and worth every penny. Was an easy install, and so glad they use an o-ring rather than RTV. Riffraff really is the best out there.

Awesome product
I had a leaking stock plenum and rather than remove and reseal and worry about leaks coming back I put these on. They are very nice and I won't have to worry about leaks or crushed inlet tubes ever again. I did have one small issue one of the plenums had been dropped on a corner it looked like it was before they got anodized it wasn't a big deal and didn't even contact Riffraff I just took a small file to the head mating surface to make sure it sat flat. I would for sure buy these again.
