Mishimoto has released a performance intercooler for the 2011+ 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 MishimotoChevrolet/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 is protected by our signature Mishimoto Lifetime Warranty.
