Y-Bridge 3.5 in. (Bridge Only) Duramax L5P Raw

High-flow 3.5" Y-Bridge for custom build racing applications. Bolts to OEM intake runners with a 3.5" Bead Roll Connection at the inlet. Constructed from 14 gauge aluminum neck with TIG welded CNC machined billet aluminum center section and flanges. Includes bungs for MAP sensor and 1/8" NPT accessory port. Standard raw aluminum finish (requires sealant to prevent oxidation), with optional custom color powder coat finishes available for an additional charge and lead time. This kit replaces the restrictive factory L5P Duramax Y-bridge, providing a larger, more direct path to the intake runners for high horsepower Duramax race engines. It is designed exclusively for use with custom fabricated racing turbocharger kits, is NOT COMPATIBLE WITH OEM PARTS, and requires additional fabrication for integration with the turbocharger intercooler system.
