Description The Banks engineers carefully examined the stock Duramax intercooler, and then upgraded everything for superior results: Stock has one plastic end tank; Techni-Cooler provides two durable, all-aluminum end tanks, which will never melt or burst under high-boost conditions Large, streamlined end tanks optimize airflow and air density With a thicker core than stock, Banks Techni-Cooler sports a 25% increase in volume. Very cool! Techni-Cooler improves cooling for higher continuous power and lower exhaust gas temps Banks’ denser air charge improves the combustion process, resulting in greater engine efficiency and better fuel economy
