Less restriction. Flows great.
The stock intercooler is riddled with restrictions that cause turbulence, which kills airflow and power. Banks minimizes restrictions by making the flow area bigger throughout, from the 3 inch mandrel-bent boost tubes to the 25% thicker core, which has a whopping 34% increase in flow volume.

Airflow cranks in Banks end tanks!
Most competitors have poorly designed sheet metal end tanks with square corners that choke airflow. Techni-Coolers large, high-efficiency custom-machined end tanks have two advantages.
One: The streamlined design and rounded corners improve airflow.
Two: Banks cast end tanks will never melt or burst under high-boost conditions.

The king of cool.
Removing restrictions and improving airflow lowers boost air temps. This increases the density and oxygen content of air entering the engine, which amplifies power, lowers exhaust gas temps (EGTs) and improves fuel economy. And when EGTs are tamed, the tuner doesnt need to limit fuel delivery. So you get higher continuous, useable power and more safe power at any EGT. Very cool!
