Wehrli 11-16 Duramax LML High Flow Bundle Kit Stage 1 - WCFab Grey

The Wehrli Custom Fabrication High Flow Intercooler Pipe Kit for 2011-2016 LML Duramax trucks upgrades airflow between the turbo and engine for improved efficiency, throttle response, and turbo spool-up. It eliminates weak points in the factory design, such as boost leaks, and includes upgraded silicone boots for higher boost pressures. The kit features a 3" high-flow passenger (cold) side upper crossover pipe (20% increase over OEM), a 3" high-flow driver (hot) side intercooler pipe, and a 3.5" high-flow passenger (cold) side intercooler pipe, all constructed from 14-gauge aluminum and finished in custom powder coat colors. It is designed for use with the OEM Y-Bridge and connects to the factory throttle valve and grid heater, requiring no tuning and fitting stock trucks without other modifications. This product offers an 18% gain in air flow over stock for the upper crossover pipe and a 23% gain for the passenger (cold) side pipe. Proudly made in the USA.
