WCFab 2001-2004 GM LB7 6.6L Duramax Stage 2 High Flow Intake Bundle Kit. Stage 2 upgrade for the 2001-2004 LB7 Duramax combines our Stage 1 High Flow Bundle and Stage 2 Intake Kit into a single package providing increased airflow for your turbo and engine for improved efficiency, throttle response, and turbo spool up. 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. The high flow, fabricated aluminum intake pipe and air box enclosure with dry filter assembly replaces the restrictive plastic factory parts on your diesel for improved engine performance.
