Optimizes the boosted air density for higher continuous power and lower exhaust gas temps. Lowers restrictions for superior flow with 25% larger core area and 34% more volume. Big boost tubes & durable cast end tanks pack cool, dense air into cylinders. Cooler EGTs, more MPG & constant-duty power. It doesn't get any cooler than Techni-CoolerLess 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-Cooler’s 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 doesn’t need to limit fuel delivery. So you get higher continuous, useable power and more safe power at any EGT. Very cool!
