Product Description
CNC Fabrication 423020 94-97 7.3L Replacement Plenum Boot Kit - Black
The CNC Fabrication 423020 Replacement Plenum Boot Kit is a direct replacement upgrade for the factory intake plenum boots found on 1994.5-1997 Ford 7.3L Power Stroke diesel engines. Manufactured from premium 5-layer aramid reinforced silicone, these heavy-duty boots are engineered to withstand elevated boost pressures, high temperatures, and the demanding conditions associated with towing, daily driving, and performance applications.
Unlike aging factory rubber boots that can crack, weaken, or leak over time, the CNC Fabrication 423020 kit features durable black silicone construction rated up to 180 PSI and includes American-made stainless steel T-bolt clamps for superior sealing and reliability. The clean black finish delivers an OEM-style appearance while providing the strength needed for stock and modified 7.3L Power Stroke builds.
