Banks Techni-Cooler Intercooler System for 2006-2010 GMC/Chevy 6.6L Duramax LLY/LBZ/LMM 25982

After Banks’ engineers carefully studied the stock intercoolers for the 2007.5-2010 GMC/Chevy 6.6L Duramax LMM and the 2006-2007 GMC/Chevy 6.6L Duramax LLY/LBZ, they decided to upgrade everything for superior results. The Techni-Cooler’s core area is bigger giving it 25% more flow volume — increasing air density for more continuous power. While the stock intercooler has one plastic end tank, the Techni-Cooler steps-up with two durable, all-aluminum end tanks, that will never melt or burst under high-boost conditions.

Key Features

• Extensively tested & validated
• Large, streamlined end tanks optimize airflow and air density
• With a thicker core sports a 25% increase in volume
• Improves cooling for higher continuous power & lower EGT
• Denser air charge improves the combustion process for greater engine efficiency & better fuel economy

Banks’ Computational Fluid Dynamics (CFD) designed, rugged cast aluminum end tanks on the Techni-Cooler insure durability and slick air flow. The same can’t be said for welded-up sheet tanks. Air doesn’t flow well with square corners, and the welds break at high boost when performance is needed the most.
