Wehrli 2011-2016 LML Duramax Passenger Side Upper Crossover Intercooler Pipe Kit WCFab- Grey

This kit includes the passenger side 3-inch high-flow upper crossover intercooler pipe, a billet turbo resonator plate for the OEM intake horn, and necessary hardware. It's designed to replace the stock pipe on your 2011-2016 LML Duramax Silverado or Sierra 2500/3500 HD, connecting to the factory throttle valve and grid heater. The larger diameter helps reduce restriction in the air intake system, which can lead to improved efficiency and quicker turbo spool-up.

The Wehrli pipe is constructed from 14-gauge aluminum and finished in a durable grey powder coat. It's designed to be a direct bolt-on upgrade that works with the factory Y-bridge and requires no additional modifications or tuning. By eliminating the factory resonator, you'll also notice a more aggressive turbo and engine sound. This part is made in the USA and is a solid option for improving your truck's breathing without needing extensive changes.

This kit is compatible with stock trucks and is best paired with emissions-compliant tuning and drop-in turbochargers if you're looking for more significant performance gains down the road. It replaces GM Part Number 12642321.
