High-efficiency intercooler engineered to reduce intake air temperatures for improved power and engine performance. Durable construction ensures optimal heat exchange, consistent boost, and a precise, reliable fit.
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.

Offered in Sleek Silver or Stealth Black, the Mishimoto 6.6L Duramax intercooler is protected by our signature Lifetime Warranty.
