Description

The Wehrli Custom Fabrication (WCFab) Stage 1 High Flow Intake Bundle Kit for 2001-2004 LB7 Duramax engines replaces restrictive OEM components with high-flow 3-inch mandrel-bent aluminum piping and a TIG-welded, CNC machined billet y-bridge base. This kit is designed to improve throttle response, turbo spool, and reduce EGTs, creating a full 3" intake tract between the turbo and the engine. It includes an FPRV Block Off Kit, silicone boots, and T-bolt clamps, and is made in the USA with a durable custom powder coat finish.
