Mishimoto 11+ Chevrolet/GMC Duramax Intercooler Kit (Black)

our engineers have maximized airflow by eliminating restrictive bends, allowing for a smooth and unimpeded airflow. The piping is constructed of mandrel bent aluminum polished to a flawless finish. This Duramax intercooler kit includes Mishimoto silicone boots with DuraCoretechnology and constant-tension T-bolt clamps for accurate and consistent holding power. Mishimoto DuraCoretechnology is the synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCoreprovides superior resistance to heat, pressure, fuel, and oil. This effectively increases the life of our boots by preventing leaks and blowouts. This package is rounded out with the Mishimoto Duramax 6.6L intercooler that features cast aluminum end tanks and a bar-and-plate core, all designed to provide cool, dense air to your engine. The Mishimoto Duramax intercooler features a 101-percent increase in core volume and is 73-percent thicker compared to the factory cooler, allowing for cooler intake temperatures, lower EGTs, and increased boost pressure tolerance. All the components in this kit are engineered to last, just like your truck. Offered with either a Sleek Silver or Stealth Black intercooler, the Mishimoto 6.6L Duramax LML Intercooler Kit is protected by our signature Lifetime Warranty.

Additional Information
