RDP Plenum Reinforcing Inserts™ 99.5-03

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.

    Easy Install

    These went in with no issue. I used a piece a 2x4 cut to go across the insert and evenly go in. Strong, sturdy material. Always the best quality from RiffRaff

    Awesome add on

    These aluminum inserts are very well designed and are a precise fit. I used a piece of wood and tapped them into place. Left me with ability to tighten away on the riff raff hoses:)

    Plenum Inserts

    Posted by Jay Delaney on Dec 30th 2020

    I discovered an intake boot that had popped off 3 days before I was to head out on a road trip. While reinstalling the boot I put one too many ugga-duggas on the clamp and damaged the plenum. I overnighted these inserts from Riffraff and got them installed without having to delay our plans. Excellent product delivered on time during the Christmas rush. Thanks guys!

    A must have!

    These are very nice parts to use in your stock intake plenums so you can upgrade your boot clamps. I hope to never have to worry about loose boots again.
    They fit perfect too!

    RDP PLENUM REINFORCING INSERTS ARE LEGIT

    Posted by Austin Brown on Dec 4th 2020

    They worked perfect. I had to barley tap them in with a rubber mallet and they made a nice snap in sound when they were seated. I will be purchasing for future projects and customer vehicles. Thanks riff raff!

    I've installed these before and sometimes you gotta tinker with the plenum opening to make them fit (NOT BECAUSE THE PART DOESN'T FIT PROPERLY) but rather the plenum has already been warped from tightening.
    THIS IS OK! I like to use a adjustable wrench and just carefully make that circle circular again! Its not bad and let's you know you needed the inserts!

    Great parts, keeps the plenum flanges from crushing and causing a boost leak
