The Wehrli Custom Fab Stage 1 high-flow intake bundle for 2017–2019 Chevrolet L5P Duramax replaces the factory two-piece intercooler plumbing with heavy-duty one-piece 3" driver and 3.5" passenger pipes. CNC-machined flanges with double O-rings, reinforced silicone boots, and stainless t-bolt clamps reduce boost leaks. It installs with basic tools, fits stock trucks, and requires no tuning.
