The Wehrli Stage 1 High Flow bundle kit for 2017–2019 L5P Duramax improves airflow between turbo and engine by replacing factory intercooler pipes with heavy duty 3" driver and 3.5" passenger pipes. It uses mandrel bends, reinforced silicone boots, stainless t-bolt clamps, a CNC machined flange with double o-rings, and retains factory sensors and connections for a bolt-on install with no tuning required. Kit finishes in custom powder coat.
