The Wehrli 3" high-flow passenger-side upper crossover intercooler pipe for 2011–2016 LML Duramax boosts airflow over the OEM piece and removes the resonator for a more aggressive turbo note. Finished in Candy Teal powder coat, it connects to the factory Y-Bridge and throttle valve, installs with basic hand tools on stock trucks, and is offered as a no-modification bolt-on component for improved intake efficiency.
