3" High Flow Y-Bridge for custom fabrication use. Not a direct OEM replacement. Does bolt to OEM intake runners. 3" Bead Roll Connection at inlet. 14 ga Aluminum neck and TIG welded CNC machined billet aluminum center section and flanges. Includes bungs for MAP sensor installation and 1/8" NPT accessory port. Raw aluminum finish - requires additional finishing after purchase to prevent oxidation. The factory LB7 Duramax Y-bridge is a significant restriction in the engine intake tract limiting the engine's efficiency and ability to make power when big air and fuel system modifications are in play. This kit provides a larger, better flowing, more direct path to the intake runners for high horsepower Duramax performance engines to help them breathe more efficiently.Shipping Notes
