Wehrli 20-25 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - Fine Texture Black

Wehrli Custom Fab is known for making well-built performance parts for diesel trucks. If you're working on your 2020-2025 Chevrolet Silverado 2500 HD or 3500 HD, or the GMC Sierra equivalent with the 6.6L L5P Duramax engine, this passenger side intercooler pipe is a solid upgrade over the factory plastic piece. The stock pipe can sometimes fail under higher boost pressures, leading to leaks and reduced performance. This pipe is designed to handle more boost reliably.

This intercooler pipe is made from 14-gauge aluminum and features a one-piece design for better airflow. It uses a CNC-machined flange with a double o-ring seal, along with a high-quality silicone boot and a black anodized billet aluminum adapter. This setup is built to withstand higher boost pressures, helping to prevent leaks and blown boots that can happen with the factory components. It also includes a threaded bung to reinstall your OEM intake temperature sensor. The fine texture black powder coating gives it a clean, finished look under the hood.

Installation is straightforward, as this pipe is designed to fit on stock trucks without needing any other modifications, upgrades, or tuning. It uses T-bolt clamps and an OEM clip ring design replacement for a secure seal.
