Wehrli Custom Fabrication WCF100867-FB 2013-2015 Cummins Upper Coolant Pipe for Dual Radiator - Fiber Blue

The Wehrli Custom Fabrication WCF100867-FB is a fabricated aluminum upper coolant pipe designed as a direct-fit replacement for the failure-prone OEM plastic Y-pipe on 2013–2015 Ram trucks equipped with the 6.7L Cummins engine and dual radiator setup. Finished in WCFab's signature Fiber Blue powder coat, this pipe combines functional durability with a clean, custom under-hood appearance.

Key Features:

• Fabricated aluminum construction — significantly more durable than the factory plastic Y-pipe it replaces
• Fiber Blue powder coat finish — corrosion-resistant, heat-tolerant finish that adds a custom look to the engine bay
• Includes silicone boots — high-temperature silicone couplers ensure leak-free, reliable connections
• Includes T-bolt clamps — heavy-duty clamps provide secure, adjustable clamping force
• Direct-fit replacement — engineered specifically for the dual radiator configuration for straightforward installation
• Made in the USA — manufactured at WCFab's facility in DeKalb, Illinois

The factory plastic coolant Y-pipe is a well-known weak point on these Cummins-powered trucks, often cracking or leaking under the heat and pressure cycles of daily driving or towing. The WCF100867-FB eliminates that vulnerability with a robust aluminum pipe that is built to last. This kit includes everything needed for installation: the aluminum pipe, silicone boots, and T-bolt clamps.
