Wehrli 17-19 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - WCFab Red

If you're working on the passenger side of your 2017-2019 Chevrolet Silverado or GMC Sierra with the 6.6L L5P Duramax engine, you've probably noticed the factory plastic intercooler pipe. This Wehrli WCFab pipe is designed to replace that stock piece with a more robust 3.5-inch aluminum pipe, aiming to improve reliability and prevent boost leaks.

This pipe is constructed from 14-gauge aluminum and features a CNC-machined flange with a double O-ring seal. It also comes with a high-quality silicone boot and stainless steel T-bolt clamps, which are designed to handle higher boost pressures better than the original plastic components. This setup helps eliminate common issues like blown boots and horsepower-robbing leaks, ensuring your turbo system performs as it should. It even includes a threaded bung to easily reinstall your factory intake temperature sensor, and it's finished in a durable WCFab Red powder coat.

The good news is that this pipe is a direct bolt-on replacement for stock trucks, meaning no additional modifications or tuning are required for installation. It's a straightforward way to upgrade a critical part of your forced induction system and improve its overall integrity.
