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.

  • Includes MAP Sensor Bung, Bracket & Seal, 1/8" NPT Accessory Port (e.g. boost), 3" Silicone Boot & Stainless Steel T-bolt Clamps, New O-Ring Flange Seals, and an FPRV Block Off Kit for Proper Clearance from Bridge to Fuel Distribution Block
  • NOTE: If running a turbo other than factory a minimum T4 pedestal height with an S300 is 5" and with an S400 is 6" for proper clearance to Y-bridge.
  • CNC Machined Billet Aluminum Center Section and Flanges - TIG Welded Construction
  • Raw Aluminum Finish - Ready for Polishing, Painting, or Custom Powder Coating
  • Made in USA
