RDP Plenum Reinforcing Inserts™ - Ford 7.3L 99.5-03
These billet 7075 Aluminum plenum inserts are a Riffraff Diesel original design and are patent pending. They are made to allow you to clamp down as hard as needed with T-bolt clamps so that you don't have any boost leaks. Fix your bent and crushed stock plenums with our Inserts as well. This is a budget friendly option to buying full billet plenums. Easy install, no special tools needed.
These were designed so as to add the least restriction possible while providing more than adequate structure for clamping. The Plenum Inserts have been machined to within .164" of the OEM diameter so there will not be any measurable affect on EGT's or cfm flow.
These are sold in a pair.

Well made product
Installed these and now I see how thin the manifold metal is. Only issue I had was getting the Y-pipe thing connected to the turbo. Since the rings effectively raise the top of that manifold some I couldn't get the Y pipe attached to the front of the turbo. And on mine the Y thing didn't perfectly line up with the manifolds either. Probably something I screwed up. I just used a grinder and made a little room and everything installed perfectly.

These are great
WOW, all other reviews are right on the money, these are amazing fit and finish are exceptional, I had the plenums off so I used my shop press and wood to press them in, perfect interference fit, however, I did put red loctite around the top lip before driving them home, RPD did this right.

Mandatory.
Crushed a plenum. Put these on. They will save you headaches later and a bunch of time pulling off the old ones and more money from replacing broken parts. Precision fit. Great part.

Impressed
Very nice craftsmanship, fit perfectly. Bought these with cac boots and a CCv kit on clays recommendation. They fit great and allowed for heavy torque on the boots. Good insurance!

After crushing my stock manifolds these came in so handy without haven't too pull everything back apart! By far one of the cheapest and best investments you can make on your 7.3
