The OEM components between the turbo and engine? Check out the WCFab Stage 1 High Flow Intake Bundle Kit for the 2001-2004 6.6L Duramax. 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.
Kit includes upgraded high quality silicone boots that withstand higher pressures and temperatures than the failure prone, angled factory parts to increase reliability and help eliminate boost leaks. Includes Fuel Pressure Regulator Valve (FPRV) Block Off Kit to allow proper clearance to larger diameter Y-bridge assembly.
