The factory LBZ/LMM Y-bridge is a poorly designed slip-in style two piece bridge with very little support that is prone to blowing apart under boost and creating poor drivability and performance. This kit is a much improved, bolt together style two piece 3" High Flow Y-Bridge designed to address the factory weak points for custom build performance and racing applications. Bolts to OEM intake runners. 3" Bead Roll Connection at inlet. Easy to install two piece bolt together design replaces separation / boost leak prone OEM part. Raw finish ready for polishing and painting standard. Custom Color Powder Coat finishes (as shown) are available as an optional upgrade and carry additional lead time.
