Wehrli 11-16 Duramax LML Passenger Side 3.5 in. Intercooler Pipe - Chevy Orange

You're getting a single-piece, 3.5-inch diameter intercooler pipe for the passenger side of your 2011-2016 Duramax LML engine. This part replaces the factory plastic pipe, which is known to be a weak point that can fail under higher boost pressures. This Wehrli pipe is finished in a durable Chevy Orange powder coat and is designed to improve airflow between your turbo and the engine.

This pipe is constructed from 14-gauge aluminum, making it a strong replacement for the stock component. It uses upgraded silicone boots and stainless steel T-bolt clamps, which are much better at sealing and can handle higher boost levels without leaking or blowing off. You'll also be able to reinstall your factory intake temperature sensor thanks to the incorporated threaded bung. It's designed to be a direct fit on stock trucks, meaning no extra modifications or tuning are needed for installation, though it pairs well with emissions-compliant tuning and drop-in turbochargers for even better performance.

This upgrade helps eliminate potential boost leaks and the horsepower loss that comes with them, while also addressing the weak points in the factory design. Installation is straightforward with basic hand tools.
