Wehrli 17-19 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - Cat Yellow

If you're working on a 2017-2019 Chevrolet Silverado or GMC Sierra with the 6.6L L5P Duramax engine, this passenger side intercooler pipe from Wehrli is a solid upgrade. It directly replaces the factory two-piece plastic pipe, which can be prone to leaks under higher boost pressures. This Wehrli pipe is a single, 3.5-inch diameter piece made from 14-gauge aluminum, designed to handle more air pressure and keep it where it needs to go.

What sets this pipe apart is its construction. It features a CNC-machined flange with a double O-ring seal, paired with a high-quality silicone boot and stainless steel T-bolt clamps. This setup is built to withstand higher boost levels than the stock components, helping to eliminate those horsepower-robbing boost leaks and prevent blown boots. It even includes a threaded bung to easily reinstall your factory intake temperature sensor, and it fits like the original, meaning no extra modifications or tuning are needed for installation.

This pipe comes in a distinctive Cat Yellow powder coat finish, adding a bit of style under the hood. It's a straightforward bolt-on part that improves reliability and sealing for your Duramax's intercooler system.
