Wehrli 3.5" passenger-side high-flow intercooler pipe for 2011–2016 LML Duramax, replacing the factory two-piece plastic pipe with a one-piece 14‑g aluminum tube. Upgraded silicone boots and stainless t‑bolt clamps resist higher boost pressures and eliminate common boost-leak failure points. The pipe includes a threaded bung for the intake temperature sensor, improves airflow and installs as a bolt-on without extra modifications.
