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.

    Hands down one of the best things you can install in your 7.3. The ability to clamp down and not have any leaks is well worth the money! Great quality and perfect fit and finish.

    Looks guys if your already working under the hood and have a chance buy these! Install them you can't go wrong. The factory plenum are weak and it will bite you in the ass when you bend them tightening the clamps. This is a great product I recommend to anyone!

    Quality Product

    Nice looking and easy install. I also bought new t bolt clamps and could finally really torque the plenums down without worrying about crushing them.

    Very easy to install and fit like a glove. Had a bent plenum from previous owner and corrected the issue. Highly recommend!
