Wehrli 20-24 Chevrolet 6.6L L5P Duramax Driver Side 3in Intercooler Pipe - Cat Yellow

When you're looking to get the most out of your 2020-2025 Chevrolet Silverado 2500 HD's 6.6L L5P Duramax engine, improving airflow to the turbocharger is a smart move. This driver side intercooler pipe from Wehrli Custom Fabrication is designed to replace the restrictive, two-piece factory pipe with a larger, single-piece 3-inch unit. This change helps the turbocharger breathe easier, which can lead to better performance.

Wehrli didn't just increase the pipe diameter; they also included upgraded silicone boots and T-bolt clamps. These components are built to handle higher boost pressures and temperatures than the stock parts, helping to prevent leaks or blown boots that can happen with modified trucks. The pipe itself features a durable, single-stage powder coating in a distinctive Cat Yellow color, adding a custom look under the hood. Best of all, this is a direct bolt-on upgrade that requires no additional modifications or tuning to your truck's computer.
