Wehrli Custom Fab 3 inch high-flow passenger-side intercooler pipe for 2004.5–2005 Chevrolet LLY Duramax. This mandrel-bent, 14 gauge aluminum replacement swaps the factory 2.5 inch part for a larger 3 inch pipe with upgraded silicone boots and stainless t-bolt clamps to better hold boost. The straight intercooler connection, custom powdercoat finish choices, and bolt-on fit provide a reliable airflow upgrade that installs with basic hand tools.
