Wehrli 17-19 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - Illusion Purple

The factory plastic intercooler pipe on your 2017-2019 Chevrolet Silverado or GMC Sierra with the 6.6L L5P Duramax engine is a known weak point, often prone to blowing apart under higher boost pressures. This 3.5-inch high-flow passenger side intercooler pipe from Wehrli Custom Fabrication directly replaces that two-piece plastic component with a robust, one-piece aluminum tube.

Crafted from 14-gauge aluminum, this pipe features a CNC-machined flange with a double O-ring seal. This design, combined with the included upgraded silicone boot and stainless steel T-bolt clamps, creates a much more reliable seal than the stock setup. This means you can confidently run higher boost pressures without worrying about horsepower-robbing leaks or the dreaded blown factory boot. It even includes a threaded bung to easily reinstall your OEM intake temperature sensor, and the durable powder coat finish adds a nice touch under the hood.

This pipe is designed as a direct bolt-on upgrade, meaning it fits your stock truck without requiring any additional modifications, tuning, or other upgrades. You get improved sealing and flow right out of the box, enhancing the reliability of your truck's forced induction system.
