Wehrli 11-16 LML Duramax Passenger Side Upper Crossover Intercooler Pipe Kit - Gloss White

This 3-inch high-flow passenger side upper crossover intercooler pipe from Wehrli is made from 14-gauge aluminum, offering a significant upgrade over the stock pipe for your 2011-2016 LML Duramax truck. The larger diameter allows for a less restricted path for air, which can lead to improved efficiency and quicker turbo spool-up. It's designed to connect directly to your factory throttle valve and grid heater, and it works with the stock Y-bridge, meaning no other modifications are needed for installation on a stock truck.

Beyond the improved airflow, which is an 18% gain over the factory part, this pipe also eliminates the factory resonator. This not only cleans up the appearance under the hood but also contributes to a more aggressive turbo and engine sound. The pipe comes finished in a durable gloss white powder coat, adding a custom look to your engine bay. Installation is straightforward with basic hand tools, and it's designed as a bolt-on part that doesn't require any tuning or additional upgrades to function correctly.

This Wehrli intercooler pipe is a solid option if you're looking to get a bit more out of your Duramax engine. While it works perfectly on a stock truck, it's also a great starting point if you plan on adding emissions-compliant tuning or a drop-in turbocharger down the road. It replaces GM part number 12642321.
