Description

The WCFab Stage 1 High Flow Intake Bundle Kit for the 2006-2007 LBZ Duramax improves airflow between the turbo and engine for enhanced efficiency, throttle response, and turbo spool-up. It eliminates weak points in the factory design that can lead to boost leaks or failures in high-performance applications. The kit features a 3" Y-Bridge Kit, an upgraded high-flow intake kit that replaces the restrictive OEM upper intake manifold. The OEM Y-bridge is a poorly designed, slip-fit style two-piece bridge prone to blowing apart under boost. This kit provides a secure sealing surface and improved airflow. It includes a 3" Hot (Driver) Side Intercooler Pipe, replacing the 2 1/2" OEM piece, and a 3.5" Cold (Passenger) Side Intercooler Pipe, replacing the failure-prone factory plastic piece. The pipes feature smooth flowing mandrel bends, CNC machined billet flanges, and double O-ring seals to withstand higher boost pressures. No tuning is required, and it's compatible with stock trucks. The kit is finished in custom powder coat colors and pairs well with emissions-compliant tuning and drop-in turbochargers for optimal performance.
