Eliminates restrictions, increasing the cooling capacity for massive continuous power. 14% more flow without starving the airflow to the radiator like our competitors! Big aluminum end tanks won't burst like the plastic stock ones.Techni-Cooler 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 Techni-Cooler delivers the maximum reduction in boost air temperature with a minimal loss of boost pressure. It doesn't get any cooler than Techni-Cooler!Banks Intercooler for the 6.4L Power Stroke produces quicker throttle response, higher continuous power at any exhaust gas temperature, better economy and a more reliable rig. It's the best aftermarket improvement you can make, especially if you climb steep hills or do heavy-duty towing.
