Description

A high-flow upgrade designed to replace the restrictive factory hot-side intercooler pipe and low-quality silicone boots on 2001-2004 LB7 Duramax. It's a one-piece 3" mandrel-bent aluminum pipe with heavy-duty straight silicone boots and T-bolt clamps, improving durability and airflow. Ideal for stock turbo trucks and those running WCFab Y-bridge and S400/stock compound turbo setups. No special tuning required.
