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

If you're looking to get the most out of your 2001-2004 Chevrolet Silverado 2500 HD with the 6.6L LB7 Duramax engine, upgrading the intercooler piping is a smart move. This driver side pipe from Wehrli replaces the restrictive factory piece and its low-quality silicone boots with a full 3-inch intake tract, helping your turbo push air more efficiently into the engine.

This pipe is a full 3-inch diameter from the turbo all the way to the engine, creating a smoother, less restricted path for charged air. Unlike the factory setup that uses angled boots, this pipe utilizes straight, high-pressure rated silicone boots and T-bolt clamps for a solid connection. The pipe itself is finished in a durable WCFab Red two-stage powder coat, which not only looks good but also holds up well under the hood. This pipe is designed to complement Wehrli's S400 over stock twin turbo kits or their LB7 Y-Bridge kits, offering a cohesive upgrade path for your Duramax.
