Wehrli 01-04 Chevrolet 6.6L LB7 Duramax Driver Side 3in Intercooler Pipe - Gloss Black

If you're working on the intercooler system for your 2001-2004 Chevrolet Silverado 2500 HD or 3500 with the 6.6L LB7 Duramax engine, this driver side intercooler pipe from Wehrli is a solid option. It's designed to replace the factory 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 larger than the stock setup. Unlike the factory pipe that uses angled boots, this Wehrli pipe uses straight, high-pressure rated silicone boots. This smoother, straighter path can help improve airflow efficiency. The pipe itself is finished in a durable gloss black powder coat, and it comes with T-bolt clamps for a secure installation.

This pipe is a direct replacement for the factory driver side intercooler pipe and is often used in conjunction with other aftermarket components like the Wehrli S400 over stock twin turbo kit or LB7 Y-Bridge kits for a more complete system upgrade.
