Wehrli 20-24 Chevrolet 6.6L L5P Duramax Driver Side 3in Intercooler Pipe - Bengal Grey

This 3-inch diameter intercooler pipe from Wehrli is built to replace the restrictive, two-piece factory pipe on your 2020-2025 6.6L L5P Duramax Silverado or Sierra. The larger diameter allows for better airflow to the engine, which can help with performance and keep things running cooler under load. It’s a single-piece design, meaning fewer connections and potential leak points compared to the stock setup.

Wehrli includes upgraded silicone boots and T-bolt clamps with this pipe. These components are designed to handle higher pressure and temperatures than the factory parts, helping to prevent the common issue of blown intercooler boots on these trucks. The pipe itself is finished in a Bengal Grey powder coat for a clean look and added durability. Installation is straightforward; it’s a bolt-on part that doesn’t require any tuning or other modifications to your truck’s stock setup.
