The Budget Y-Bridge Kit is an upgraded high flow intake kit for the 2001-2004.5 LB7 Duramax. The factory LB7 Y-bridge measure's only 2 3/8" ID, this high flow bridge is a full 3" Inlet for more airflow and increased horsepower. We take a factory cold side inter cooler pipe and factory Y-bridge and modify them so you have a full 3" tract from inter cooler to the engine. This is our most cost effective Y-bridge kit for the LB7 and works well for removing the EGR on LB7's equipped with them. If you're looking for the next best upgrade option, check out the WCFab LB7 Stage 3 Y-Bridge Kit.
