Superior to stock, everything about Banks Techni-Cooler Intercooler system is bigger. It includes mandrel-bent high-flow boost tubes - large, high-efficiency all-aluminum end tanks - a wide-open inlet and outlet - a thicker core area with an improvement in volume. Banks Intercooler dramatically increases the cooling capacity by balancing the richer fuel mixture with greater airflow and cooler, denser air. Denser air has more oxygen, which improves combustion as well as engine efficiency. Result: higher continuous power and more power at any exhaust gas temp (EGT), better fuel economy and lower EGTs. That's a truckload of benefits! Banks Intercooler delivers the maximum reduction in boost air temperature with a minimal loss of boost pressure. It doesn't get any cooler than Banks Techni-Cooler! Mounting hardware included.
