Wehrli 17-19 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - Bengal Blue

Wehrli Custom Fabrication is known for making well-built parts for diesel trucks, and this passenger side intercooler pipe for your 2017-2019 6.6L L5P Duramax Silverado or Sierra is a prime example. It replaces the factory two-piece plastic pipe with a single, 3.5-inch diameter piece made from 14-gauge aluminum. This upgrade is designed to handle higher boost pressures, helping to prevent the common issue of blown factory boots and boost leaks that rob your engine of power.

This pipe features a CNC-machined flange with a double O-ring seal, ensuring a much more reliable connection than the stock setup. It also includes an upgraded silicone boot and stainless steel t-bolt clamps, which are built to withstand increased boost. You'll also find a threaded bung to easily reinstall your OEM intake temperature sensor. The best part is that it's a direct bolt-on part, meaning no additional modifications, tuning, or upgrades are needed for installation, and it uses the factory clip ring design for the intercooler outlet connection.

This pipe comes in a durable Bengal Blue powder coat finish. It's a solid option for improving the reliability of your Duramax's intercooler system.
