The Wehrli Custom Fab Stage 1 high-flow intake bundle for 2017–2019 Duramax L5P replaces the factory two-piece intercooler piping with one-piece heavy-duty 3" driver and 3.5" passenger tubes. Made in the USA from 14 ga. aluminum with mandrel bends, it uses reinforced silicone boots, stainless t-bolt clamps and a CNC-machined flange with double O-rings to eliminate boost leaks. Installs with basic hand tools and requires no tuning.
