WCFab Wehrli Custom Fab 3" High Flow Upper Crossover Intercooler Pipe Kit Gloss Black for 2011-2016 GM 2500HD/3500HD (LML Duramax) WCF100328-GB

Fits 2011-2016 Chevrolet Silverado and GMC Sierra 2500HD/3500HD (LML-6.6L Duramax) trucks.

The WCFab 3-inch High Flow Passenger Side Upper Crossover Intercooler Pipe is designed to eliminate the restrictive factory plastic resonator and improve intake efficiency. Constructed from 14g aluminum, this 3-inch pipe provides an 18% gain in airflow over the stock component, resulting in faster turbo spool-up and improved engine responsiveness. By deleting the resonator, this kit also provides a more aggressive turbo and engine sound while cleaning up the appearance of the engine bay.

This kit is a direct bolt-on replacement for GM Part Number 12642321 and is compatible with the factory Y-bridge, throttle valve, and grid heater. It requires no additional tuning or modifications for installation, making it an ideal upgrade for both stock and modified trucks. The pipe is finished in a durable Gloss Black powder coat for long-lasting corrosion resistance.
