Wehrli's passenger‑side 3.5 in. high‑flow intercooler pipe for 2011–2016 LML Duramax replaces the factory two‑piece plastic with a one‑piece 14‑gauge aluminum pipe and upgraded silicone boots to withstand higher boost pressures. The bolt‑on component improves airflow, turbo response, and reliability while eliminating common boost‑leak failure points; it installs with basic hand tools and is finished in custom powder colors.
