Shop with Blessed Performance for the Banks Power Techni Cooler Intercooler System for your 2004-2005 GM 6.6L LLY Duramax diesel. 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! Mounting hardware included.
Note:
Banks Techni-Cooler comes with an all black appearance.
