Wehrli Custom Fab 3-inch Y-Bridge (bridge only) for Chevrolet LBZ/LMM Duramax engines replaces the OEM slip-in bridge with a two-piece, bolt-together design that bolts to OEM intake runners. The high-flow bridge reduces the risk of separation under boost, includes O-ring seals at the inlet, and ships in a gloss black finish. It’s offered as a reinforced drop-in replacement for custom and racing builds.
