Product Description
CNC Fabrication 423008 99.5-03 7.3L Billet Plenums Raw Aluminum
The CNC Fabrication 423008 Billet Intake Plenum Set is a premium upgrade for 1999.5-2003 Ford 7.3L Power Stroke diesel engines. Precision CNC machined from high-strength 6061-T6511 aircraft-grade aluminum, these billet intake plenums provide improved durability, enhanced appearance, and superior resistance to deformation compared to the factory stamped steel plenums.
Designed for both stock and high-performance applications, the CNC Fabrication billet plenums feature thicker wall construction to withstand elevated boost pressures while maintaining proper sealing and intake airflow. These raw aluminum plenums are compatible with aftermarket HPOP line kits, fuel system upgrades, and are commonly used on T4 turbo conversion setups for OBS and Early 1999 Power Stroke applications utilizing 3-inch intake plumbing.
