Upgrade your Chevy/GMC 6.6L Duramax engine with the Banks Power Oil Cooler Upgrade, designed to deliver superior heat reduction and performance for 2001-2007 and 2011-2019 models. This innovative system improves heat rejection by 31% or more, with older Duramax engines experiencing the greatest gains. At the core of the upgrade is the advanced GM 2020 Duramax L5P oil cooler, which boasts a 22% improvement in heat rejection at factory-rated 450 horsepower compared to earlier models, and an impressive 31% greater heat reduction at 600 horsepower and higher RPMs.

The upgraded 19-plate cooler significantly outperforms older 10, 11, or 14-plate factory units by increasing surface area and improving oil flow for better heat transfer and consistent oil pressure. This enhanced cooling capability ensures your engine runs cooler, even under heavy loads or high-performance conditions, reducing wear and extending engine life.

Banks pairs this system with the premium AMSOIL EAO17 oil filter, offering exceptional filtration with 99% efficiency at 20 microns and minimal oil pressure loss. The kit also includes all necessary hardware, gaskets, and a pre-installed 1/8" NPT port for easy integration of oil temperature or pressure sensors, making it a comprehensive and ready-to-install solution.

Please note, this kit is not compatible with late 2007.5-2010 LMM Duramax engines due to enhanced EGR cooling systems. Equip your Duramax with this upgrade to ensure optimal cooling and peak performance in any driving condition.
