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

If you're looking to get the most out of your 2001-2004 Duramax LB7 engine, especially if you're upgrading your turbo system, replacing the factory driver side intercooler pipe is a smart move. The stock pipe and its silicone boots can be a weak point, especially under increased boost. This Wehrli Custom Fab pipe is built to handle more, offering a full 3-inch intake tract all the way from the turbo to the engine.

This pipe replaces the factory component with a larger, smoother 3-inch diameter tube, which helps improve airflow and can complement other upgrades like a Y-bridge kit or a larger turbo. It uses straight, high-pressure rated silicone boots instead of the factory's angled ones, reducing the chance of leaks or blow-offs. The pipe itself is finished in a durable gloss white powder coat, adding a clean look under the hood and resisting corrosion.

This kit comes with the 3-inch pipe, the necessary silicone boots, and T-bolt clamps for a secure installation. It's designed as a direct replacement for the driver's side pipe, making it a straightforward upgrade for your truck.
