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.

    They are well built and fit nice and snug. I was able to tighten the new boots much tighter than before.

    Great product, easy installation (considering you have to remove everything involved). The inserts were tight going in (are not much smaller in diameter than the sheet metal intake manifolds) and gave me the ability to really tighten my boots. This has eliminated my boost leaks.

    Whether you're replacing boots or removing and reinstalling for whatever reason, just get these. They make a huge difference in confidence level and they're almost idiot proof.
