Wehrli 20-24 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - Illusion Purple

When you're looking to improve the reliability of your 2020-2025 Chevrolet Silverado 2500 HD or 3500 HD, especially those with the 6.6L L5P Duramax engine, upgrading the intercooler piping is a smart move. The factory plastic pipe can sometimes struggle under higher boost pressures, leading to leaks or even failure. This Wehrli Custom Fab passenger side intercooler pipe is designed to replace that stock component with a more robust aluminum piece.

This 3.5-inch diameter pipe is constructed from 14-gauge aluminum, offering a significant strength improvement over the original plastic. It features a CNC machined flange with a double O-ring seal, paired with a high-quality silicone boot and a black anodized billet aluminum adapter. This setup is built to handle increased boost pressures more effectively, helping to prevent leaks and ensure consistent performance. It also incorporates a threaded bung to easily reinstall your OEM intake temperature sensor. The pipe is finished in a durable Illusion Purple powder coat.

This intercooler pipe is designed as a direct bolt-on upgrade for stock trucks, meaning no additional modifications or tuning are required for installation. It uses T-bolt clamps and O-rings for a secure seal, replacing the factory clip ring design for improved long-term reliability.
