Wehrli 17-19 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - Gun Metal

When you're working on your 2017-2019 Chevrolet Silverado or GMC Sierra with the 6.6L L5P Duramax engine, addressing the intercooler piping is a smart move. The factory's two-piece plastic pipe can be a weak point, especially if you're running higher boost pressures. This Wehrli 3.5-inch passenger side intercooler pipe is built to handle that, replacing the stock plastic with a solid, one-piece aluminum tube.

This pipe is well-built with 14-gauge aluminum and features a CNC machined flange that uses a double O-ring seal. This setup is designed to hold higher boost pressures more reliably than the factory setup, helping to prevent those frustrating boost leaks and blown boots. It also includes a place to reinstall your factory intake temperature sensor and comes with a high-quality silicone boot and stainless steel t-bolt clamps for a strong seal. It's a direct bolt-on replacement that doesn't require any additional modifications or tuning for installation.

This pipe is a solid option for improving the reliability of your Duramax's intercooler system. It's designed to fit right on stock trucks, making the installation straightforward. Just remember that this part is not CARB approved and cannot be shipped to California.
