Mishimoto has expanded their Duramax performance parts line to include the performance intercooler for the 2011-2016 Chevrolet/GMC 6.6L Duramax LML. High intake and exhaust gas temperatures can reduce performance and potentially cause engine damage. Protect your investment by upgrading to the Mishimoto 6.6L Duramax LML intercooler. This Duramax intercooler is precision engineered with durable cast aluminum end tanks and an efficient bar-and-plate core, all designed for improved airflow, lower intake temperatures, and improved EGTs.

The Mishimoto Duramax intercooler will support substantial boost pressure in your stock or highly modified truck. Pair your intercooler with the Mishimoto Chevrolet/GMC 6.6L Duramax Intercooler Pipe and Boot Kit for even more protection against boost pressure. The Duramax LML intercooler features a 101% increase in core volume and is 73% thicker compared to the factory cooler. Offered in Sleek Silver or Stealth Black, the Mishimoto 6.6L Duramax intercooler, like all of our Duramax performance parts, is protected by our signature Mishimoto Lifetime Warranty.
