Wehrli 17-19 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - Fine Texture Black

If you're working on a 2017-2019 Chevrolet Silverado or GMC Sierra 2500/3500 HD with the 6.6L L5P Duramax engine, this Wehrli Custom Fab passenger side intercooler pipe is a solid upgrade over the stock setup. The factory two-piece plastic pipe can be a weak point, especially when you're running higher boost pressures. This pipe swaps that out for a single, larger 3.5-inch diameter pipe made from 14-gauge aluminum, which helps improve airflow into the engine.

Wehrli builds this pipe with a CNC-machined flange that uses a double O-ring seal, along with a high-quality silicone boot and stainless steel t-bolt clamps. This setup is designed to hold higher boost pressures more reliably than the factory components, helping to prevent leaks and blown boots. It also includes a threaded bung to easily reinstall your factory intake air temperature sensor, and it's designed as a direct bolt-on replacement that doesn't require any additional modifications or tuning for installation.

This pipe comes with a fine texture black powder coat finish for a clean look under the hood. It's a straightforward replacement that can help ensure your intercooler system is working efficiently and reliably.
