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

This is the Wehrli 3-inch high-flow passenger side upper crossover intercooler pipe kit for your 2011-2016 LML Duramax Silverado or Sierra 2500/3500 HD. This part replaces the stock pipe, which can be a restriction in your engine's air intake system. By increasing the pipe diameter by about 20% over the OEM part, this kit helps reduce air flow restriction, leading to improved efficiency and a quicker turbo spool-up. It also removes the factory resonator, which can give your turbo and engine a more aggressive sound.

The pipe is constructed from 14-gauge aluminum for a strong yet lightweight build, and it's finished in a durable gloss black powder coat. It connects directly to your factory throttle valve and grid heater, and it's designed to work with the stock Y-bridge. This means it's a bolt-on upgrade that doesn't require any other modifications, tuning, or special tools for installation, making it a straightforward way to improve your truck's performance. It's a popular choice for stock trucks or those paired with emissions-compliant tuning and drop-in turbochargers.
