Wehrli 11-16 Duramax LML Passenger Side 3.5 in. Intercooler Pipe - Gun Metal

Starting with a 14-gauge aluminum construction, this Wehrli intercooler pipe is built to handle more boost than the factory plastic piece. For your 2011-2016 Duramax LML truck, this passenger side pipe replaces the stock two-piece unit with a single, high-flow 3.5-inch diameter pipe. This design helps improve airflow between the turbo and the engine, which can lead to better throttle response and quicker turbo spool-up.

The factory intercooler pipes are known weak points, especially when running higher boost pressures. This Wehrli pipe uses upgraded silicone boots and stainless steel t-bolt clamps to create a more reliable seal, preventing horsepower-robbing boost leaks and the frustration of blown factory boots. It also includes a threaded bung to reinstall your OEM intake temperature sensor, and it's designed to work with your stock Y-bridge and crossover pipe, meaning no extra modifications or tuning are needed for installation on a stock truck.

This pipe is finished in a durable gunmetal powder coat. While it bolts right on to a stock truck, it pairs well with emissions-compliant tuning and drop-in turbochargers if you're looking to maximize performance gains down the road.
