The Wehrli Custom Fab Stage 3 High Flow Intake Bundle is a complete upgrade for 2001–2004 Chevrolet 6.6L LB7 Duramax trucks, finished in Kiwi Green. The kit replaces restrictive OEM Y-bridge and intercooler piping with fabricated aluminum 3" and 4" mandrel-bent piping, a TIG-welded billet y-bridge and a dry filter with pre-filter cover to improve airflow to the turbo, throttle response and intake temperatures.
