Chevrolet Silverado 3500 HD Intercooler Pipe and Boot Kit - Cold-Side - Mishimoto - DuraCore Technology - Polished - `11-`15. This cold-side intercooler pipe and boot kit is a direct-fit upgrade for 2011–2015 6.6L Duramax trucks, replacing the fragile factory plastic pipe with durable aluminum and reinforced silicone boots.

The Mishimoto cold-side pipe uses 3.5" mandrel-bent aluminum with a polished finish and a two-piece design for easier installation and removal. A CNC-machined AIT sensor bung lets you retain the factory inlet air temperature sensor. The kit removes restrictive factory bends to improve airflow and thermal management, while Mishimoto DuraCore silicone provides increased resistance to heat, pressure, fuel, and oil to reduce the risk of leaks or blowouts. Included constant-tension T-bolt clamps provide consistent clamping force for reliable sealing. This kit is made in the USA and carries Mishimoto's lifetime warranty.
