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

If you're looking to make sure your 2017-2019 Chevrolet Silverado 2500 HD or GMC Sierra 2500/3500 HD with the 6.6L L5P Duramax engine is running at its best, this passenger side intercooler pipe from Wehrli is a solid upgrade. It replaces the factory two-piece plastic pipe with a single, larger 3.5-inch aluminum pipe designed to handle more boost without issues.

This pipe is well-built with a CNC machined flange that uses a double O-ring seal, along with a high-quality silicone boot and stainless steel T-bolt clamps. This setup is much more reliable than the stock clip ring and boot, helping to prevent those horsepower-robbing boost leaks and blown boots that can happen under higher pressure. It even includes a threaded bung to reinstall your factory intake temperature sensor, and the gloss black powder coat finish looks sharp under the hood.

The best part is that this pipe is a direct bolt-on for stock trucks. You won't need any extra modifications or tuning to get it installed and working, making it a straightforward way to improve the integrity of your intercooler system.
