The Wehrli Stage 1 High Flow Bundle is a direct-fit upgrade for 2020–2025 L5P 6.6L Duramax trucks that replaces the factory two-piece intercooler plumbing with heavy-duty one-piece 3" driver and 3.5" passenger pipes. Made from 14 ga. aluminum with mandrel bends, the kit uses reinforced silicone boots, stainless t-bolt clamps, and a CNC-machined flange with double O-rings to reduce boost leaks and improve flow. Installs with basic tools.
