GMC Sierra 2500 HD Intercooler Pipe and Boot Kit - Mishimoto - Hot-Side, DuraCore - Polished (2011–2015). This direct-fit hot-side upgrade replaces the restrictive factory 2.5" plumbing with a larger 3.0" mandrel-bent aluminum pipe to improve airflow and reduce exhaust gas temperatures.

Designed specifically for 2011–2015 6.6L Duramax-equipped Sierra and Silverado heavy-duty trucks, this Mishimoto kit is a two-piece, bolt-on replacement that maintains factory routing while increasing flow. The polished aluminum construction resists corrosion and is ready for daily use or build-ups. Mishimoto DuraCore silicone boots provide enhanced resistance to heat, pressure, fuel, and oil, reducing the chance of leaks or boot failure. Included constant-tension T-bolt clamps deliver consistent clamp force where it matters most. This hot-side pipe is an ideal companion to Mishimoto intercoolers and is made in the USA with Mishimoto’s lifetime warranty.
