Wehrli 3" high-flow passenger-side intercooler pipe for 2004.5–2005 LLY Duramax. Replacing the factory 2.5" pipe, this mandrel-bent 14ga aluminum one-piece pipe and upgraded silicone boots reduce weak points that cause boost leaks and failures. The straight boot connection at the intercooler increases reliability. It bolts on to stock trucks without other modifications, improves airflow and turbo response, and installs easily with basic hand tools for a durable cold-side upgrade.
