Stock 7.3 Intake Plenums leave much to be desired. Made from a thin press formed sheet metal, they are prone to leak between the mounting bolts, inlets get crushed or boots easily blow off of them. Beans Diesel Bean Machine has resolved all of these issues as well as improving air flow and performance. By redesigning them, we can now attain much better air flow over factory intakes. With the machined aluminum surface, you get a perfect seal to the head while also being very rigid. These may sound expensive, but they are quite economical compared to the frustration of blown boots or having to re-seal stock sheet metal, plus they just look killer!
