Description

The WCFab 2001-2004 GM LB7 6.6L Duramax Stage 3 High Flow Intake Bundle Kit is a comprehensive upgrade that replaces the OEM Y-Bridge, intercooler pipes, and air intake components with high-flow mandrel-bent aluminum piping and a fabricated air box. It includes a 4" turbo intake horn, silicone boots, FPRV block-off kit, and a 3" high-flow down pipe. The kit is designed to increase airflow for improved efficiency, throttle response, and turbo spool up, and is compatible with OEM and upgraded drop-in IHI style turbochargers.
