Wehrli 11-16 Duramax LML Passenger 3in. Upper Crossover Intercooler Pipe - Bengal Red

Starting with 14-gauge aluminum construction, this Wehrli 3-inch upper crossover intercooler pipe is built to handle the demands of your 2011-2016 LML Duramax. It replaces the factory passenger side pipe, offering a significant improvement over the stock component. The larger 3-inch diameter allows for a substantial 18% increase in airflow compared to the OEM part, which can lead to a more efficient engine and quicker turbo spool-up.

This pipe also eliminates the factory resonator, contributing to a more aggressive turbo and engine sound. It's designed to connect directly to your factory Y-bridge, throttle valve, and grid heater, meaning no additional modifications or upgrades are needed for installation on a stock truck. The durable Bengal Red powder coat finish not only looks sharp but also adds a layer of protection. While it works perfectly on its own, it pairs well with emissions-compliant tuning and drop-in turbochargers for even greater performance gains.

Installation is straightforward with basic hand tools, and no tuning is required for this bolt-on upgrade. This part replaces GM part number 12642321.
