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.

    Great product!

    Posted by Nick on May 22nd 2016

    I had a pool of oil on the top of the engine. I cleaned it all up, replaced all CAC hoses with new RiffRaft hoses and inserted the reinforcements, tighten everything down. Not a bite of oil 500 miles later. Who knows how long they had been leaking.
    Great product, great customer service, Thank you,
    Nick

    Good upgrade

    These are a tight fit in the factory plenum. After a little persuasion they are in and are not coming out. Good upgrade for the thin plenum

    Used these when I did boost system upgrade, fit very well, added strength to a weak spot. Torqued down hard on the boots with no worries.

    Function and form is Perfect!

    This allows you o use a good set of t-clamps and make sure you have got a good tight seal around those intake boots without damaging the plenums

    Great idea and excellent fit

    I was replacing my CAC boots after a turbo swap and decided to install these inserts, it is a great peace of mind to know you can tighten these down and not damage the plenum. The OEM plenums will bend very easily and become out of round, don't let this happen or you will develop a boost leak. Great product and easy install, Highly recommend it.
