Wehrli 11-16 Chevrolet 6.6L LML Duramax Driver Side 3in Intercooler Pipe - Illusion Blueberry

If you're working on your 2011-2016 Chevrolet Silverado 2500 HD or 3500 HD, or the GMC Sierra equivalent, this 3-inch driver side intercooler pipe from Wehrli is a solid upgrade over the stock setup. The factory pipe is a two-piece design that necks down to 2.5 inches, which can really restrict airflow. This Wehrli pipe is a single, larger 3-inch piece, helping your engine breathe easier, especially if you've already upgraded your turbo or are planning to. It's finished in a cool Illusion Blueberry powder coat, which adds a custom look under the hood.

Beyond just being bigger, this pipe comes with upgraded silicone boots. The factory boots can sometimes fail under higher boost or temperature, leading to leaks. These upgraded boots are built to handle more pressure and heat, offering improved reliability and helping to prevent those frustrating blown boot issues. This pipe is designed to work with the factory turbocharger or any direct drop-in replacement, making it a straightforward swap for most LML Duramax owners.
