High Flow Bundle Intake Kit Stage 2 01-04 Duramax LB7 Flat Black

This Stage 2 upgrade for the 2001-2004 LB7 Duramax combines Wehrli's Stage 1 High Flow Bundle and Stage 2 Intake Kit into a single package. It provides increased airflow for the turbo and engine for improved efficiency, throttle response, and turbo spool up. It 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 increase throttle response, turbo spool up, and reduce EGTs by creating a full 3" intake tract between the turbo and engine.
