Product Description
CNC Fabrication 423005 94.5-98.5 7.3L Billet Plenums - Black
The CNC Fabrication 423005 Billet Intake Plenum Kit is a premium upgrade for 1994.5-Early 1999 Ford 7.3L Power Stroke engines. Manufactured from high-strength 6061-T6511 aircraft-grade aluminum, these billet intake plenums provide superior durability, improved clamping strength, and a cleaner underhood appearance compared to the factory stamped steel plenums.
Designed and CNC machined in-house by CNC Fabrication, these billet plenums eliminate the flex and deformation commonly seen with factory sheet metal units when tightening charge air cooler boots. Featuring a durable black powder-coated finish, thicker wall construction, and compatibility with aftermarket HPOP and fuel line kits, the 423005 plenum set is ideal for stock, towing, and high-boost performance applications.
