3-inch mandrel-bent high flow boost tubes. Eliminates restrictions for an 18% increase in flow, dramatically increasing the cooling capacity for massive continuous power, big aluminum end tanks won't burst like the plastic stock ones. Banks Techni-Cooler Intercooler system includes mandrel-bent 3" high-flow boost tubes ... large, high-efficiency all-aluminum end tanks instead of the wimpy stock plastic ones that can rupture under high-boost conditions ... a high-flow inlet that distributes air evenly across the intercooler for an 18% increase in flow and more effective cooling ... a wide-open outlet ... and a thicker core area with impressive volume. Techni-Cooler provides the maximum reduction in boost air temperature with a minimal loss of boost pressure. Cooling the air makes it denser and more oxygen rich, improving combustion and engine efficiency. Result: higher continuous power and more power at any exhaust gas temp (EGT), better fuel economy and lower EGTs. What could be cooler than that? Mounting hardware included.
