# Banks Power 04-05 Chevy 6.6L LLY Techni-Cooler System Optimizes the boosted air density for higher continuous power and lower exhaust gas temps. Restriction-free 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-Cooler 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. 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 inch 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. 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! Everything about Banks Intercooler is bigger, it doesn't get any cooler than Banks Intercooler. Key Features: Optimizes air pressure and distribution going into the intake manifold.
