RDP Plenum Reinforcing Inserts™ - Ford 7.3L 94-Early 99
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.

Amazing product!
This helped me out tremendously, not only was the fit perfect (you will need to use a rubber mallet to get them seated) but I was able to crank down on the T-bolt hose clamps and stop my boost leak. Even if you truck is stock I highly recommend these, with the inlets being reinforced you can make sure you won’t have a leak there!

Mandatory Mod
Really not an option for those think, tin plenum intakes. Mine were bent and these straightened them right out on my Early 1999 7.3L. I really recommend them if you don't want boost leaks.

Good quality
Good quality help you be able to tighten down the clamps so your turbo y boots don’t slip off easy to put in just put them in a little and tap them in with a rubber mallet I would recommend hem to any one with an obs 7.3
