About this part

Product Details

Wehrli Custom Fabrication is known for making well-built parts for Duramax trucks. This 3-inch driver side intercooler pipe is designed for 2004.5 through 2010 LLY, LBZ, and LMM Duramax engines. It replaces the factory 2.5-inch pipe, which can be a bottleneck for airflow, especially when you're running higher boost levels than stock.

The factory intercooler pipe often uses a bead roll design at the turbo connection that can blow off under increased boost. This Wehrli pipe uses straight, high-pressure rated silicone boots and T-bolt clamps for a more secure connection, even with more air pressure. The full 3-inch diameter allows for better airflow from the turbocharger to the intercooler, helping your engine breathe easier. It’s finished in a durable Candy Red two-stage powder coating to resist corrosion and look good under the hood.

This pipe fits a range of popular Duramax trucks, including the Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD models from 2004 to 2010. It’s a solid option if you’re looking to improve the airflow on your Duramax.
