What are the benefits of upgrading my Duramax intercooler?

Upgrading your intercooler helps lower intake air temperatures and reduce exhaust gas temperatures (EGTs). This can lead to improved engine performance and helps protect your engine from damage caused by excessive heat, especially when running higher boost pressures.

What is the difference in size compared to the stock intercooler?

This Mishimoto intercooler features a core volume that is 101-percent larger than the factory intercooler. It is also 73-percent thicker, allowing for significantly more efficient heat dissipation.

If you're looking to protect your 6.6L Duramax LML engine from high temperatures, this intercooler is a solid upgrade.
