Chevrolet Silverado 3500 HD Intercooler Pipe and Boot Kit - Mishimoto - Hot-Side, DuraCore - Polished - `11-`15. A direct bolt-on hot-side upgrade for 6.6L Duramax trucks designed to reduce restrictive bends and increase airflow with a polished 3.0" mandrel-bent aluminum pipe.

This Mishimoto kit replaces the factory 2.5" hot-side pipe with a 3" diameter two-piece design that smooths airflow into the intercooler. The larger piping can improve airflow, contributing to measurable gains in power and reductions in exhaust gas temperatures when paired with appropriate supporting mods. The kit uses Mishimoto DuraCore silicone boots for improved resistance to heat, pressure, fuel and oil, and includes constant-tension T-bolt clamps for reliable clamping force. Finished in polished aluminum and made in the USA, the kit carries Mishimoto's lifetime warranty.

Fits Chevrolet and GMC 6.6L Duramax trucks from 2011-2015, including Silverado and Sierra 2500/3500 HD trim levels. This hot-side pipe is an ideal companion to upgraded intercoolers and other intake/modification work and does not require additional tuning on its own.
