Wehrli 01-04 Chevrolet 6.6L LB7 Duramax Driver Side 3in Intercooler Pipe - WCFab Grey

When you're working on your 2001-2004 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with the 6.6L LB7 Duramax engine, this Wehrli Custom Fab driver side intercooler pipe is what you get in the box: a full 3-inch pipe, straight high-pressure silicone boots, and T-bolt clamps. It's designed to replace the stock pipe and its less robust silicone boots, aiming for a more consistent flow from the turbo to the engine.

This pipe creates a full 3-inch intake tract, which is a step up from the factory setup that often uses angled boots. The straight, high-pressure rated boots are built to handle the demands of boosted air, and the included T-bolt clamps ensure a solid connection. The pipe itself features a custom two-stage powder coating in WCFab Grey, adding a layer of durability and a clean look under the hood. This setup is a good complement if you're looking to upgrade your twin turbo system or Y-bridge.
