Wehrli's passenger-side 3.5" intercooler pipe for 2011–2016 LML Duramax replaces the factory plastic two-piece with a high-flow, one-piece 14-ga aluminum 3.5" pipe. It uses upgraded silicone boots and stainless t-bolt clamps to better hold higher boost pressures and eliminate boost leaks. The bolt-on pipe improves airflow and throttle response, fits stock trucks without modifications, installs with basic tools, and is made in the USA.
