Wehrli 11-16 Duramax LML Passenger Side 3.5 in. Intercooler Pipe - Illusion Purple

Wehrli Custom Fabrication is known for making solid parts for Duramax trucks. This passenger side intercooler pipe is a prime example, designed to replace the factory plastic piece on your 2011-2016 LML Duramax Silverado or Sierra. The stock pipe can be a weak point, especially if you're running higher boost pressures, leading to leaks or even failure. This upgraded pipe addresses that directly.

Crafted from 14-gauge aluminum, this 3.5-inch pipe offers a smoother, more direct path for air coming from the turbo to the engine. This improved airflow can lead to better throttle response and quicker turbo spool-up. It uses high-quality silicone boots and stainless steel t-bolt clamps, which are much better at holding higher boost pressures than the original equipment. Plus, it includes a threaded bung to easily reinstall your factory intake temperature sensor, and it's finished in a cool Illusion Purple powder coat.

This pipe is a straightforward bolt-on upgrade that doesn't require any other modifications or tuning to see benefits, making it a solid option for stock trucks or those with emissions-compliant tuning and drop-in turbochargers. It's designed to fit right with the OEM Y-bridge and crossover pipe.
