Description

The Wehrli Custom Fabrication (WCFab) WCF100693 is a 3-inch Y-Bridge Kit designed for 2001-2004 Chevrolet 6.6L LB7 Duramax engines. This kit replaces the restrictive OEM Y-bridge and cold-side intercooler pipe with a high-flow 3-inch design, aiming to increase throttle response and turbo spool-up by creating a full 3-inch intake tract from the intercooler outlet to the engine. It also eliminates the angled OEM intercooler boots that are prone to failure and includes an FPRV Block off kit for proper clearance to the larger diameter Y-bridge.
