Wehrli Custom Fab 3 inch high-flow passenger-side intercooler pipe for 2004.5–2005 Chevrolet LLY Duramax. It replaces the factory 2.5 inch one-piece pipe with a mandrel-bent, 14 gauge aluminum 3 inch unit and uses upgraded silicone boots and stainless t-bolt clamps to resist higher boost pressures. The straight intercooler connection, powdercoat finish option, and bolt-on fit make installation simple with basic hand tools.
