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

This is the driver side 3-inch intercooler pipe from Wehrli Custom Fabrication, designed for 2004.5 through 2010 Chevrolet and GMC trucks with the 6.6L LLY, LBZ, or LMM Duramax diesel engines. It's a direct replacement for the stock 2 1/2-inch pipe, which can be a bottleneck for airflow, especially when you're running higher boost levels. The factory pipe's reverse bead roll design at the turbo connection is also known to blow off under increased pressure, something this updated pipe addresses by using straight, high-pressure rated silicone boots.

Wehrli builds this pipe as a single piece, which helps promote better airflow compared to multi-piece designs. It's finished with a custom two-stage powder coating in Illusion Purple, giving it a unique look under the hood. The kit includes the necessary silicone boots and T-bolt clamps, ensuring a solid connection that's less likely to separate under boost. This upgrade is a popular choice for Duramax owners looking to improve the efficiency of their intercooler system.
