Wehrli 04.5-10 Chevrolet 6.6L LLY/LBZ/LMM Duramax Driver Side 3in Intercooler Pipe - Illus Blueberry

This Wehrli intercooler pipe starts with a full 3-inch diameter, replacing the factory 2.5-inch pipe that can restrict airflow, especially on modified Duramax engines. The factory pipe often uses a reverse bead roll at the turbo connection, which can be prone to blowing off under higher boost levels. Wehrli addresses this by using straight, high-pressure rated silicone boots with T-bolt clamps for a more secure connection that holds tight even when you're pushing more boost.

The pipe itself is constructed from durable steel and finished with a custom two-stage powder coating in an Illus Blueberry color, adding a unique look under the hood. This upgraded pipe is designed to fit a range of Chevrolet and GMC trucks from 2004 to 2010, including models like the Silverado 2500 HD and Sierra 3500 HD. It's a solid option for anyone looking to improve the performance and reliability of their Duramax's intercooler system.
