Give Your Duramax The Cold Side It Deserves

If you're still relying on the stock plastic cold-side pipe in your Duramax, you're leaving performance and reliability on the table. Mishimoto’s Cold Side Intercooler Pipe and Boot Kit is a direct-fit upgrade built to handle the kind of pressure a tuned diesel throws down. With 3.5-inch mandrel-bent aluminum construction, this pipe delivers smoother airflow and eliminates the weak points found in the factory setup. You’ll get better throttle response, lower EGTs, and more consistent boost under heavy load. Whether you’re towing uphill, pulling a trailer, or hammering the throttle on the open road, this kit is built to handle it all. The included DuraCore boots and constant-tension clamps give you extra confidence that nothing’s coming loose or blowing apart under pressure. It’s the kind of upgrade you install once and rely on for the long haul.

Precision Fit And Performance Backed By Proven Engineering

The Mishimoto MMICP-DMAX-11CBK kit is engineered for 2011–2016 Duramax LML trucks and is designed to deliver both increased reliability and measurable performance gains. At the core is a 3.5-inch mandrel-bent aluminum pipe, which helps reduce airflow restrictions compared to the factory design. This pipe also features a CNC-machined AIT sensor bung, allowing you to retain your factory sensor without modifications. The two-piece design makes installation and future maintenance far easier, especially in tight engine bays. Included in the kit are Mishimoto’s DuraCore silicone boots, which are internally lined with a high-resistance synthetic layer that stands up to oil, fuel, heat, and boost pressure far better than standard silicone. The constant-tension T-bolt clamps help maintain a consistent, leak-free seal even as temperatures fluctuate. With all components made in the USA and backed by Mishimoto’s lifetime warranty, this cold-side kit is a no-compromise solution for long-term performance.
