Wehrli 3in Y-Bridge Kit | Duramax LB7 (WCF100615-RAW)

The Wehrli 01-04 Chevrolet Duramax LB7 S300/S400 Single Turbo 3in Y-Bridge Kit is a high-flow Y-bridge designed for custom fabrication applications. Constructed from 14-gauge aluminum with a TIG-welded CNC machined billet aluminum center section and flanges, this kit features a 3-inch bead roll connection at the inlet for secure attachment. It includes bungs for MAP sensor installation and a 1/8-inch NPT accessory port, providing enhanced airflow capabilities. The raw aluminum finish requires additional finishing to prevent oxidation. This Y-bridge addresses the factory LB7 Duramax's restrictive intake design, offering a larger, more efficient flow path to improve engine breathing and power potential when paired with larger air and fuel systems.

Designed for 2001-2004 Chevrolet Duramax LB7 engines, this Y-bridge kit bolts directly to OEM intake runners but is not a direct OEM replacement. It is intended for high-performance applications, including custom setups and modifications aimed at increasing horsepower and airflow efficiency. Suitable for use in performance builds, the kit facilitates improved intake flow, helping engines produce more power under demanding conditions. Installation involves custom fabrication, and the kit includes all necessary components for a secure fit. It is ideal for enthusiasts seeking to optimize their Duramax's intake system for maximum performance.
