Chevrolet Silverado 2500 HD Intercooler Pipe and Boot Kit - Cold-Side - Mishimoto - DuraCore Technology - Polished - `11-`15. A direct-fit cold-side upgrade for 2011–2015 6.6L Duramax trucks, designed to replace the factory plastic pipe and silicone boot for improved durability under heat and pressure.

This Mishimoto cold-side intercooler pipe is built from 3.5" mandrel-bent aluminum with a polished finish and a two-piece design for easier installation and service access. The kit removes the restrictive bends found in the OE plumbing to improve airflow, which can help with charge cooling and exhaust gas temperatures when paired with other supporting mods. It includes a CNC-machined bung for the factory AIT sensor so the sensor can be retained, Mishimoto DuraCore silicone boots for superior resistance to heat, fuel and oil, and constant-tension T-bolt clamps for consistent holding power. Made in the USA and backed by Mishimoto's lifetime warranty, this kit is engineered for owners who want a robust, long-lasting replacement for the stock cold-side components.
