Product Description

The GMC Sierra Intercooler Pipe and Boot Kit - Cold-Side by Mishimoto, reference code MMICP-DMAX-17CWBK, is the ultimate upgrade for your 2017-2019 Chevrolet/GMC 6.6L Duramax L5P. Finished in a sleek wrinkle black, this kit is engineered to enhance airflow and boost your engine's power and efficiency.

Elevate the performance of your Duramax engine with this expertly designed cold-side intercooler pipe and boot kit. The factory-installed cold-side pipe is limited to a 2.5-inch diameter with tight bends, resulting in restrictive air passage. Mishimoto’s specially constructed 3-inch mandrel-bent aluminum pipes create smoother transitions to significantly enhance airflow, unlocking more power potential from your engine. The two-piece design mimics the factory setup for straightforward installation.

Moreover, this kit features high-quality silicone boots incorporating Mishimoto’s DuraCore™ technology, an advanced synthetic material that provides superior resistance to heat, pressure, fuel, and oil. This innovation extends the lifespan of your boots by preventing leaks and blowouts, while constant-tension T-bolt clamps ensure consistent and reliable holding power. Additionally, a CNC-machined quick-disconnect fitting with a new O-ring and spring clip guarantees a secure, leak-free installation. Unlike other cold-side pipes on the market, Mishimoto’s design retains the intake air temp harness mounting location for safe and secure routing.
