Product Description
CNC Fabrication 423002 99.5-03 7.3L Intake Plenum Reinforcement Bushings 3 Inch Inlet
The CNC Fabrication 423002 Intake Plenum Reinforcement Bushing Kit is designed to strengthen the factory intake plenums on 1999.5-2003 Ford 7.3L Power Stroke engines equipped with 3-inch intercooler inlet connections. Manufactured from aircraft-quality billet aluminum, these reinforcement bushings help prevent distortion, deformation, and crushing of the factory stamped steel intake plenums when tightening intercooler boots and clamps.
Factory intake plenums can become damaged when higher clamp loads are applied during maintenance, performance upgrades, or intercooler boot replacement. The CNC Fabrication 423002 bushings provide additional structural support to help maintain proper sealing and plenum integrity while improving long-term durability. Designed specifically for the 7.3L Power Stroke platform, this kit includes bushings for both the driver and passenger side intake plenums.

FAQ
What do the CNC Fabrication 423002 bushings do?
These billet aluminum bushings reinforce the factory intake plenums and help prevent them from being crushed or distorted when tightening intercooler boots and clamps.
Will these fit my 2002 7.3L Power Stroke?
Yes. The CNC Fabrication 423002 kit is designed for 1999.5-2003 Ford 7.3L Power Stroke applications equipped with 3-inch inlet plenums.
Why are plenum reinforcement bushings important?
The factory intake plenums are constructed from stamped sheet metal and can deform under excessive clamp pressure. These bushings help maintain plenum shape and sealing integrity.
How many bushings are included?
The kit includes two bushings—one for the driver side plenum and one for the passenger side plenum.
What material are the bushings made from?
The bushings are precision-machined from aircraft-quality billet aluminum for strength and durability.
Do these require modification to install?
No. These bushings are designed as a direct-fit reinforcement solution for factory-style intake plenums with 3-inch inlet connections.
