Wehrli 20-25 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - Bengal Silver

If you're looking to improve the airflow and reliability of your 2020-2025 Chevrolet Silverado 2500 HD or 3500 HD with the 6.6L L5P Duramax engine, this passenger side intercooler pipe from Wehrli Custom Fabrication is a solid option. It directly replaces the factory two-piece plastic pipe, which can be a weak point under higher boost pressures.

This pipe is constructed from 14-gauge aluminum and features a larger 3.5-inch diameter for improved airflow. The factory plastic pipe is replaced with a single piece, reducing potential leak points. It includes a CNC-machined flange with a double O-ring seal and upgraded silicone boots with black anodized billet aluminum adapters. These components are designed to handle higher boost pressures, helping to prevent blown boots and boost leaks that can occur with the stock setup. The Bengal Silver powder coating adds a nice touch and helps protect the aluminum.

Installation is straightforward as it's designed to be a direct bolt-on replacement, requiring no additional modifications, upgrades, or tuning. It also incorporates a threaded bung to easily reinstall your OEM intake temperature sensor.
