Chevrolet Silverado 3500 HD Intercooler Pipe and Boot Kit - Mishimoto 6.6L Duramax, Includes hot-side and cold-side pipes with silicone boots and T-bolt clamps - Polished - 11-15. A direct bolt-on upgrade for 6.6L Duramax trucks, this Mishimoto kit replaces restrictive factory piping with larger, mandrel-bent aluminum tubes and durable silicone boots.

This kit is designed to improve airflow through the charge system on 2011–2015 6.6L Duramax trucks. By replacing the stock pipes that contain multiple restrictive bends, the Mishimoto pipes increase internal diameter on both hot and cold sides, which can improve power delivery and help lower exhaust gas temperatures (EGTs) when paired with supporting modifications. The kit includes Mishimoto DuraCore silicone boots for better resistance to heat, pressure, fuel, and oil, plus constant-tension T-bolt clamps for reliable sealing under boost.
