Description

The WCFab Stage 1 High Flow Intake Bundle Kit for the 2001-2004 6.6L Duramax is designed to improve performance and efficiency by replacing restrictive OEM components. This kit includes a high flow, 3" mandrel bent aluminum piping kit, feeding WCFab's signature TIG welded, CNC machined billet y-bridge base to increase throttle response, turbo spool up, and reduce EGTs. It also features upgraded high-quality silicone boots for increased reliability and to eliminate boost leaks. An FPRV (Fuel Pressure Regulator Valve) Block Off Kit is included for proper clearance. This kit replaces the restrictive OEM LB7 Y-bridge, passenger side intercooler pipe, and driver side intercooler pipe with a high flow, 3" mandrel bent aluminum piping kit feeding WCFab's signature TIG welded, CNC machined billet y-bridge base to help increase throttle response, turbo spool up, and reduce EGTs by creating a full 3" intake tract between your turbo and engine.
