WEHRLI CUSTOM FAB WCF100164 2007.5-2010 LMM DURAMAX HIGH FLOW 3" Y-BRIDGE KIT

Product Description

Improve airflow and performance on your Duramax with the WEHRLI CUSTOM FAB WCF100164 2007.5-2010 LMM DURAMAX HIGH FLOW 3" Y-BRIDGE KIT. This premium upgrade replaces the restrictive factory intake bridge with a high-flow fabricated aluminum 3-inch Y-bridge designed to increase intake airflow and support higher horsepower builds.

The factory LMM Duramax intake bridge is known to create a major airflow restriction, especially when larger turbochargers, upgraded tuning, or performance injectors are installed. Wehrli Custom Fabrication engineered this kit with smooth mandrel-bent aluminum construction and precision CNC machined connections to deliver improved airflow, reduced restriction, and better throttle response.
