Wehrli 2011-2016 LML Duramax Passenger Side Upper Crossover Intercooler Pipe Kit Gloss Black

The Wehrli 2011-2016 LML Duramax Passenger Side Upper Crossover Intercooler Pipe Kit is a high-performance upgrade designed to enhance airflow and engine efficiency. Constructed with a 3-inch diameter high-flow pipe, it offers a 20% increase in size over the OEM component, reducing restrictions and promoting better turbo spool-up. The kit eliminates the resonator for a more aggressive turbo and engine sound, while also improving the appearance. Finished in your choice of custom powder coat colors, this intercooler pipe is a durable, direct-fit replacement that connects seamlessly to the OEM Y-Bridge, factory throttle valve, and grid heater, requiring no additional modifications or tuning for installation.

Designed for 2011-2016 LML Duramax trucks, this intercooler pipe is compatible with stock vehicles and is ideal for street and performance applications. It pairs best with emissions-compliant tuning and drop-in turbochargers to maximize gains. Installation is straightforward using basic hand tools, making it suitable for both DIY enthusiasts and professional installers. The kit replaces GM Part Number 12642321 and is intended for use with stock trucks requiring no further upgrades, providing a reliable upgrade for improved airflow, efficiency, and sound characteristics.
