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.
Riffraff Diesel Performance is committed to 100% Made in the USA on this product. All materials are from USA resources. Every machining step is performed in the USA. Every component is assembled in the USA.

Just what I needed
I was having trouble collapsing the intake plenums on my new motor build, these sleeves solved that problem perfectly.
-
Awesome upgrade!
Why International and Ford would allow such flimsy metal in the stock intake is beyond me...Never fear RiffRaff is here! This is a MUST HAVE! my plenum was leaking and out of round do to the clamps squashing them! I recommend that ALL Powerstroke owners install these!

A must have if you upgrade any boots
These are a home run. If you have ever seen the cheap metal Ford used for the intake then you will want to buy these for your setup.

quality product
Took some doing to put it. That's a good sign of the tight tolerances they where made with. Awesome job

Worth Every Cent
Fortunately, my 01 still had original everything on it, so no one had bent up my plenums before. A couple of TPS on a block of wood with a dead blow hammer, and they were in. Was able to crank those T clamps down good and tight!

Sweeet!
Very nice. To bad you cannot see them once installed. Nice looking parts! Like the ability to crank down on the band clamps.
