What is the main benefit of upgrading to the Banks Techni-Cooler System?

The main benefit is optimizing boosted air density. This leads to higher continuous power output and lower exhaust gas temperatures (EGTs) by reducing restrictions in the airflow path compared to the stock intercooler.

Are the boost tubes included in this kit powder-coated?

Yes, the boost tubes included in this Banks Power Techni-Cooler System are red powder-coated. This adds durability and a distinct look under the hood.

What makes the Banks end tanks different from stock or other brands?

Banks uses custom-machined, durable cast end tanks with a streamlined design and rounded corners to improve airflow. Unlike many competitors' sheet metal end tanks, Banks' cast tanks are built to withstand high-boost conditions without melting or bursting.

Product Details

You get the Banks Power Techni-Cooler System in this Banks Power intercooler kit. It's built to optimize boosted air density for higher continuous power and lower exhaust gas temperatures. If you're running a 2002-2004 Chevrolet Silverado 2500 HD or 3500, or a 2002-2004 GMC Sierra 2500 HD or 3500 with the 6.6L Duramax LB7 engine, this system replaces the restrictive stock intercooler and boost tubes.

The stock intercooler has restrictions that cause turbulence and kill airflow. Banks addresses this with a 25% thicker core that has 34% more volume, along with 3-inch mandrel-bent boost tubes. The custom-machined cast end tanks are designed with streamlined shapes and rounded corners to improve airflow, unlike the sheet metal end tanks found on many competitor kits. These cast end tanks are also stronger and won't melt or burst under high-boost conditions.
