Chevrolet Silverado 2500 HD Intercooler Pipe and Boot Kit - Mishimoto (6.6L Duramax, `11-`15) is a direct bolt-on replacement that upgrades the factory intercooler piping. This polished mandrel-bent aluminum kit replaces restrictive OE bends with larger-diameter piping for improved airflow on 2011–2015 6.6L Duramax trucks.

The kit includes both hot-side and cold-side pipes sized to optimize flow (3.0" hot-side, 3.5" cold-side), Mishimoto silicone boots with DuraCore inner layer, and constant-tension T-bolt clamps for reliable sealing under boost. Manufactured in the USA, these polished aluminum pipes reduce intake restriction compared to stock plumbing, helping improve airflow and supporting lower exhaust gas temperatures (EGTs) when combined with other performance upgrades. This kit is designed to work with the Mishimoto 6.6L Duramax Performance Intercooler and is a straightforward install for enthusiasts looking to refine turbo response and charge efficiency without major modifications.
