Wehrli Custom Fab Stage 1 high-flow bundle kit for 2020–2024 Duramax L5P trucks. This kit replaces fragile OEM intercooler piping with heavy-duty 3" driver-side and 3.5" passenger-side one-piece aluminum pipes, CNC machined flange with double O-rings, upgraded silicone boots and stainless t-bolt clamps. It improves flow and durability, installs with basic tools, fits stock trucks and saves $25 versus buying components separately.
