2001-2004 LB7 Duramax Stage 1 High Flow Intake Bundle Kit

Already have an air intake and turbo down pipe that you're happy with, but looking to improve your LB7's performance and efficiency by addressing weak points in 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.

***NOTE: Not Compatible BANKS INTERCOOLER assemblies. If you have a Banks intercooler, please use Y-bridge kit WCF100640 (Call to order).***

***NOTE: If running an aftermarket turbo other than factory IHI style, a minimum T4 pedestal height with an S300 is 5" and with an S400 is 6" for proper clearance to Y-bridge.***
