Banks Power 08-10 Ford 6.4L Techni-Cooler SystemEliminates restrictions, dramatically increasing the cooling capacity for massive continuous power. 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
