The Wehrli Custom Fab 3" Y-Bridge kit is an upgraded high-flow replacement for the OEM upper intake bridge on 2006–2007 LBZ Duramax trucks. This bolt-together two-piece bridge and 3" intercooler pipes eliminate OEM slip-fit weaknesses, improve sealing, provide smooth mandrel bends, CNC-machined flanges, and includes silicone boot, T-bolt clamps and sensor seals for a direct-fit, no-tuning-required upgrade that works with stock lower passenger-side pipe.
