Wehrli 17-19 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - Semi-Gloss Black

If you're working on your 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 stock plastic setup. The factory two-piece pipe can be a weak point, especially when running higher boost pressures, leading to leaks or even blown boots. This pipe addresses that by replacing it with a single, well-built 3.5-inch aluminum pipe.

Wehrli uses a CNC machined flange with a double o-ring seal, combined with a high-quality silicone boot and stainless steel t-bolt clamps, to ensure a strong seal that can handle more boost without leaking. This means you get improved reliability and can eliminate those horsepower-robbing boost leaks that the stock pipe might allow. It's designed to fit directly onto stock trucks, so you won't need any extra modifications or tuning to get it installed and working.

This pipe also includes a threaded bung to easily reinstall your OEM Intake Temperature Sensor, keeping your factory monitoring systems functional. The durable semi-gloss black powder coat finish looks good under the hood and adds a layer of protection.
