WCFab 2001-2004 GM LB7 6.6L Duramax Stage 3 High Flow Intake Bundle Kit Stage 3 upgrade for the 2001-2004 LB7 Duramax combines the Stage 1 High Flow Bundle, Stage 2 Intake Kit, and 3" Down Pipe into a single package providing increased airflow for your turbo and engine for improved efficiency, throttle response, and turbo spool up.
