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.

    riffraffs got are back with this good part. nothing should be thin on a diesel. You should take your time putting these in and use a dead blow hammer real easy.

    Fantastic product!

    You will not believe how amazingly well these fit into the OE intake. They are tapered to start easily and go in like a dream. This is a sub-$40 part that could easily save you from digging through your 200+ degree motor on the side of the road after you blow a boot. It is a no-brainer!

    Easy to install and allows you to tighten clamps much tighter so the boots don't come off.

    Essential Upgrade

    Did not appreciate importance until CAC boot kit arrived and began to dissemble. Immediately stopped, ordered RPI's and clamps. Quality products and highly recommend both!

    Very easy to install and are excellent quality. My intake plenums were in perfect condition so the inserts slipped right in.
