Wehrli 11-16 Duramax LML P/S 3.5in. Intercooler Pipe - Candy Red

Starting with a 14-gauge aluminum construction, this Wehrli intercooler pipe is built to handle more boost than the stock plastic piece on your 2011-2016 Duramax LML. The factory two-piece pipe is a known weak point that can lead to leaks, especially when you're pushing your truck harder. This one-piece, 3.5-inch pipe is designed to improve airflow between the turbo and the engine, which can lead to better throttle response and quicker turbo spool-up.

Wehrli replaces the factory clip ring design with high-quality silicone boots and stainless steel t-bolt clamps. This setup offers a more reliable seal and is much better at holding higher boost pressures, preventing those horsepower-robbing leaks. It also includes a threaded bung so you can easily reinstall your factory intake temperature sensor. The candy red powder coat finish looks sharp under the hood and resists corrosion.

This pipe is a direct bolt-on replacement for your stock truck, meaning no extra modifications or tuning are required for installation. It's designed to work with your OEM Y-bridge and crossover pipe. While it works great on a stock truck, it pairs particularly well with emissions-compliant tuning and drop-in turbochargers if you're looking for more performance gains down the road.
