Wehrli Custom Fabrication WCF100693-SGS Duramax Y-Bridge Kit Turbocharger Intercooler Pipe Set - 3 LB7

The Wehrli Custom Fabrication WCF100693-SGS is a complete high-flow 3" Y-Bridge kit designed specifically for 2001-2004 LB7 Duramax engines. This kit replaces the restrictive factory Y-bridge and cold side intercooler pipe to create a full 3" intake tract from the intercooler outlet to the engine, increasing throttle response and turbo spool-up while providing 50% more airflow than the OEM upper intake manifold.

Key Features:

• 3" fabricated billet aluminum Y-Bridge clearanced for OEM-style intake horn
• Compatible with factory IHI turbo and aftermarket drop-in IHI style chargers
• 3" passenger side intercooler pipe with 14-gauge mandrel bent aluminum construction
• FPRV (Fuel Pressure Regulator Valve) block-off kit included
• Complete hardware: silicone boots, T-bolt clamps, O-ring bridge flange gaskets
• MAP sensor seal and hold-down bracket included
• Durable powder coat finish in Satin Gun Smoke gray color
• Made in the USA with TIG-welded construction

This complete Y-Bridge kit eliminates the angled OEM intercooler boots that are prone to failure and provides a significant improvement in airflow performance. Each component is precision-engineered for direct-fit installation and manufactured in WCFab's state-of-the-art facility in DeKalb, Illinois.
