What is the main benefit of upgrading the intercooler on my Duramax truck?

Upgrading your intercooler, like this Mishimoto kit, significantly lowers intake air temperatures. Cooler air is denser, which allows your engine to produce more power and helps reduce Exhaust Gas Temperatures (EGTs), especially under heavy load or when towing.

What makes the Mishimoto silicone boots different from standard silicone boots?

These Mishimoto silicone boots feature DuraCore technology, an advanced synthetic material. DuraCore provides superior resistance to heat, pressure, fuel, and oil compared to regular silicone, which helps prevent leaks and blowouts and increases the lifespan of the boots.

Does this intercooler kit come with all the necessary hardware for installation?

Yes, this kit includes the intercooler, all necessary intercooler piping, silicone boots, and constant-tension T-bolt clamps. It is designed as a complete replacement for your factory intercooler system.

Product Details

If you're looking to get more out of your 2011-2016 Chevrolet Silverado or GMC Sierra 6.6L Duramax LML, Mishimoto has developed a substantial intercooler kit to help. This kit is designed to tackle high Exhaust Gas Temperatures (EGTs) and keep your engine running cool, even when you're pushing it hard. It's a complete package aimed at improving airflow, significantly reducing air charge temperatures, and supporting your truck's power output at any level.

The intercooler piping in this kit is a key component, featuring mandrel-bent aluminum pipes that have been polished to a smooth finish. Mishimoto engineers worked to eliminate restrictive bends, allowing for a smooth and unimpeded flow of air. These pipes are paired with Mishimoto silicone boots that use DuraCore technology. This synthetic material is built to resist heat, pressure, fuel, and oil, which helps prevent leaks and blowouts, extending the life of the boots. The kit also includes constant-tension T-bolt clamps to ensure a secure and consistent hold. The heart of the system is the all-aluminum intercooler itself, featuring cast aluminum end tanks and a bar-and-plate core. This design is built to deliver cool, dense air to your engine. Compared to the factory cooler, this Mishimoto intercooler boasts a 101% increase in core volume and is 73% thicker, which translates to cooler intake temperatures, lower EGTs, and better tolerance for increased boost pressure.

This kit comes in a stealth black finish and is backed by Mishimoto's Lifetime Warranty. Please note that this kit is not CARB approved and cannot be shipped to California.
