Techni-Cooler® Intercooler System


Move over, pipsqueak.
The stock intercooler has an inferiority complex. No wonder—it’s smaller than Techni-Cooler in every aspect: boost tubes … core area … inlet/outlet … even the end tanks. And most competitors use poorly designed sheet metal end tanks and provide inadequate flow volume.

Banks cranks up the volume.
Banks improves airflow into and out of the intercooler with big mandrel-bent 3” boost tubes. Large, rugged, high-efficiency cast end tanks that won’t rupture under high-boost conditions. A huge inlet and outlet. And a 25% larger core area with a whopping 34% improvement in volume.

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 power at any EGT. Very cool!
