Product Description
CNC Fabrication 423001 94-98.5 7.3L 2 Inch Inlet Intake Plenum Reinforcement Bushings
The CNC Fabrication 423001 Intake Plenum Reinforcement Bushings are designed to strengthen the factory intake plenums on 1994-1998.5 Ford 7.3L Power Stroke diesel engines equipped with 2-inch inlet plenums. Manufactured from aircraft-quality billet aluminum, these reinforcement bushings help prevent the factory stamped steel intake plenums from becoming crushed, distorted, or damaged when tightening intercooler and charge air cooler boots.
Over time, increased boost pressure, aftermarket CAC boots, and repeated service can place additional stress on factory intake plenums. The CNC Fabrication 423001 bushings provide added support at the clamping surface, helping maintain proper sealing and reducing the risk of boost leaks caused by plenum deformation. Designed specifically for OBS and Early 1999 7.3L Power Stroke applications, these bushings are a simple and effective upgrade for both stock and performance-oriented trucks.

FAQ
What do the CNC Fabrication 423001 bushings do?
These bushings reinforce the factory intake plenums and help prevent them from becoming crushed or distorted when tightening charge air cooler boots.
Will these fit my OBS 7.3L Power Stroke?
Yes. These bushings are designed for 1994-1998.5 Ford 7.3L Power Stroke applications equipped with factory 2-inch inlet intake plenums.
How many bushings are included?
The kit includes two bushings, one for the driver side intake plenum and one for the passenger side intake plenum.
Why are reinforcement bushings beneficial?
Factory stamped steel plenums can deform when clamps are overtightened. Reinforcement bushings help maintain plenum shape, improve sealing, and reduce the likelihood of boost leaks.
What material are these bushings made from?
The CNC Fabrication 423001 bushings are manufactured from aircraft-quality billet aluminum for strength, durability, and long service life.
Are these recommended for performance applications?
Yes. These bushings are commonly used on stock, towing, tuned, and performance-oriented 7.3L Power Stroke builds where boost pressure and clamp loads may exceed factory conditions.
