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

If you're looking to get more airflow to your Duramax engine, especially if you've been running higher boost levels, this driver side intercooler pipe from Wehrli Custom Fabrication is a solid option. It's designed to replace the stock 2 1/2 inch pipe with a full 3 inch diameter, which helps reduce restriction and can improve performance. This pipe fits a range of Chevrolet and GMC trucks from 2004 to 2010, including models like the Silverado 2500 HD and Sierra 3500.

The factory intercooler pipe has a bead roll design at the turbo connection that can sometimes blow off under increased boost. Wehrli addresses this by using straight, high-pressure rated silicone boots and T-bolt clamps, creating a more secure connection. The pipe itself is finished in a durable gloss white powder coat, which not only looks good but also helps protect the metal. This is a well-built piece that’s designed to handle more demanding conditions than the stock component.
