Wehrli High Flow Bundle Kit Stage 1 3.5 in. 13-18 Cummins 6.7L Semi-Gloss Black Semi-Gloss Black 100423-SGB

The Wehrli Stage 1 High Flow Bundle Kit for 2013-2018 6.7L Cummins 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 complete failures in demanding applications. The kit replaces the restrictive factory pipes with heavy-duty, high-flowing 3.5" diameter, 14-gauge aluminum pipes featuring smooth, aerodynamic mandrel bends. It includes upgraded 5-ply silicone boots designed to withstand higher pressures and temperatures than the factory boots, increasing reliability and preventing blown factory boots. This kit is made in the USA and is compatible with stock trucks, requiring no tuning. It is not compatible with Banks Intercoolers. The hot side pipe shows a 51% increase in airflow and the cold side pipe a 44% increase in airflow compared to OEM components.
