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

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 over the factory plastic piece. The stock two-piece plastic pipe can be a weak point, especially when running higher boost pressures, leading to leaks and reduced performance. This pipe addresses that by replacing it with a single, 3.5-inch diameter aluminum pipe.

Wehrli builds this pipe with a CNC machined flange that features a double o-ring seal, which, along with the included upgraded silicone boot and stainless steel t-bolt clamps, creates a much more reliable seal than the factory setup. This helps prevent horsepower-robbing boost leaks and eliminates the common issue of blown factory boots. It's designed to be a direct bolt-on replacement, meaning you can reinstall your factory intake temperature sensor into the integrated bung and use the included wire clip for the intercooler outlet connection without needing any additional modifications or tuning.

The durable Bengal Silver powder coat finish not only looks good but also adds a layer of protection. This pipe is a straightforward way to improve the reliability and sealing of your Duramax's intercooler system.
