The Wehrli Custom Fab Stage 1 high-flow intake bundle is a bolt-on upgrade for 2007.5–2010 LMM Duramax engines that replaces the OEM y-bridge with a two-piece 3" Y-bridge and includes a 3" driver-side intercooler pipe and a 3.5" passenger-side intercooler pipe. The kit uses CNC-machined flanges, improved silicone boots with stainless T-bolt clamps, and supplies required hardware; it flows substantially better than stock and is offered with a custom powder-coat finish.
