The Wehrli Custom Fab 3in Y-Bridge Kit for 2007.5-2010 LMM Duramax replaces the OEM upper intake manifold with a high-flow, bolt-together two-piece bridge that secures the air inlet horn and eliminates the slip-fit failure points. Smooth mandrel bends and CNC billet flanges deliver a continuous 3in tract from intercooler to engine while keeping factory grid heater, throttle valve and EGR connections.
