Improves Stock Design

It's no secret that your GM Duramax loves to breathe loads of fresh, cool air. After years of faithful service, treat your engine to the upgrade it deserves with the Banks Techni-Cooler System. This system is designed to optimize and boost air density for higher continuous power and lower exhaust gas temperatures. The 25% thicker core area translates to 34% more flow volume. One of the highlights of the Techni-Cooler is its mandrel-bent 3-inch boost tubes. These tubes are thoughtfully engineered to accommodate the increased volume of air flowing through the system smoothly. Additionally, the system is equipped with all-aluminum end tanks that provide superior durability compared to the weak, plastic stock counterpart. The result is better throttle response, increased power, and improved Duramax efficiency.

Designed for High-Performance Applications

The Banks Techni-Cooler System is designed for your 2004.5-2005 GM 6.6L Duramax to keep its cool for the ultimate performance.

For an added layer of protection against disastrous corrosion and wear, the large boost tubes feature a striking red powder-coat finish, leaving you with an eye-catching pop of color under the hood. Furthermore, installation is simple and hassle-free, whether you're a professional mechanic or a DIY enthusiast. With all necessary mounting hardware included, you can get this upgrade up and running quickly and confidently. For additional peace of mind, Banks covers this product with their 2 Year Warranty.
