Description

***BRIDGE ASSEMBLY ONLY*** 3" High Flow Y-Bridge for custom build racing applications only. Bolts 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 finish ready for polishing or painting standard. Custom Color Powder Coat finishes are available as an optional upgrade and carry additional lead time. 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 race engines to help them breathe more efficiently. INCLUDES FPRV BLOCK OFF KIT TO ALLOW CLEARANCE OF LARGER BRIDGE TO FUEL PRESSURE DISTRIBUTION BLOCK. ***NOTE: Raw finish selection will require some type of finish / sealant to prevent oxidation***
