Wehrli 20-24 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - WCFab Grey

This 3.5-inch, 14-gauge aluminum intercooler pipe from Wehrli Custom Fabrication is built to handle more boost than the factory plastic piece on your 2020-2025 L5P Duramax. The factory two-piece pipe can sometimes fail under higher pressure, leading to leaks or blown boots. This one-piece design aims to prevent that, keeping your turbo system sealed and running efficiently.

It features a CNC machined flange with a double O-ring seal, ensuring a solid connection that resists boost leaks. Wehrli also includes an upgraded silicone boot and a black anodized billet aluminum adapter, which work together to hold higher boost pressures reliably. The pipe also has a threaded bung to accept your factory intake temperature sensor, and it uses a T-bolt clamp system for a secure seal. This pipe is designed as a direct bolt-on replacement, meaning it fits your stock truck without needing any other modifications, tuning, or upgrades.

The pipe is finished with a durable WCFab Grey powder coat. This is a straightforward upgrade that improves the reliability of your intercooler system.
