Banks 25984 Intercooler SystemTechni-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. A lot of guys claim their intercoolers are the best. But do they have the guts to test their product against its toughest rival? Banks has. We discovered that no other product delivers charge air power like our newest Techni-Cooler does in all three of these critical areas. If an aftermarket intercooler can't deliver a boost increase over the stock unit, there's no point in taking it out of the box. Techni-Cooler delivered over . It's Mechanical Engineering 101. Cold, dense intake air means more oxygen and lower EGT's. It improves economy and unlocks your fuel's power making ability. Techni-Cooler delivered over 5% more air density! Super-thick intercoolers block vital airflow to the vehicle radiator, resulting in high temps that cause the ECU to cut back fuel, leaving you with de-rated power and heat-related breakdowns. Techni-Cooler delivered over 14% more flow without starving the airflow to the radiator! That's what you call a win-win-win situation. Banks 6.4L Power Stroke Techni-Cooler is the unit that's been tested and proven to beat the competition on all three counts. The intercooler 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.
