Wehrli Custom Fabrication WCF100860-GRY Billet Aluminum Y-Bridge Grey

The Wehrli Custom Fabrication WCF100860-GRY is a billet aluminum Y-bridge (intake manifold crossover pipe) finished in a striking grey anodize. Engineered as a direct upgrade over the factory plastic OEM unit, this WCF Y-bridge is precision-machined from high-grade billet aluminum to deliver improved airflow, superior durability, and long-lasting performance under the demanding conditions of turbocharged diesel engines.

The factory plastic Y-bridge is a well-documented weak point on affected Duramax platforms — prone to cracking and splitting under elevated boost pressure and heat cycling. Wehrli's billet replacement eliminates these failure points entirely, providing a rigid, leak-free connection between the intercooler and intake manifold.

Key Features:

• Precision CNC-machined from billet aluminum for maximum strength and longevity
• Grey anodized finish for corrosion resistance and appearance
• Direct OEM replacement — bolt-on installation with no cutting or modification required
• Supports higher boost pressure compared to the fragile factory plastic unit
• Manufactured in the USA by Wehrli Custom Fabrication
• Available in multiple anodized color options to match your engine bay build

Whether you're running a stock tune or a high-powered built diesel, the Wehrli Custom Fabrication WCF100860-GRY Y-Bridge is a foundational upgrade that protects your intake tract and adds a custom touch under the hood. Backed by WCF's reputation for quality diesel performance fabrication.
