Product Details
This 3-inch diameter intercooler pipe from Wehrli is built to replace the restrictive, two-piece factory 2 1/2-inch pipe on your 2011-2016 Chevrolet Silverado 2500 HD or 3500 HD, and GMC Sierra 2500 HD or 3500 HD with the 6.6L LML Duramax engine. The larger diameter and smoother, one-piece design help improve airflow to the engine, which can make a difference in how your truck performs, especially when you're asking it to work hard.
Wehrli includes upgraded silicone boots and T-bolt clamps with this pipe. The silicone boots are designed to handle higher pressure and temperatures than the stock ones, helping to prevent blow-offs that can happen with the factory setup. This means a more reliable connection and less chance of losing boost pressure. The pipe itself is finished in a custom single-stage powder coating in Cat Yellow, giving your engine bay a distinct look.
This pipe is compatible with the factory turbocharger or any drop-in style replacement turbo. Please note that this part is not CARB approved and cannot be shipped to California.
