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

This Wehrli 3-inch driver side intercooler pipe is built with a single-stage powder coating in Bengal Red, offering a strong finish that resists corrosion. It replaces the factory 2 1/2-inch pipe, which can be a bottleneck for airflow, especially when 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 avoids by using straight, high-pressure rated silicone boots and T-bolt clamps for a secure connection.

This pipe is designed for LLY, LBZ, and LMM Duramax engines found in Chevrolet Silverado and GMC Sierra trucks from 2004 to 2010. By stepping up to a full 3-inch diameter, it allows for a less restricted path for the compressed air coming from the turbocharger to reach the intercooler. This improved flow can help maintain better air temperatures and support more consistent power delivery under load. The included silicone boots and T-bolt clamps ensure a solid seal, preventing boost leaks that can rob your engine of performance.
