The Wehrli 3" high-flow passenger-side upper crossover intercooler pipe for 2011–2016 LML Duramax increases airflow over stock and eliminates the resonator for improved appearance and sound. Finished in WCFab Red powder coat, it mates to the OEM Y-Bridge and factory throttle valve, installs easily on stock trucks without extra upgrades, and includes hardware and a billet turbo resonator plate for a bolt-on intercooler enhancement.
