Banks CoolRunner™ Oil Pan - GM Duramax 6.6L L5P (2017-2019)

The Banks CoolRunner™ Oil Pan uses technology from Banks's military engine program to extend oil life on the 2017-2019 GM Duramax 6.6L L5P. It rejects more heat and reduces oil aeration compared to stock, adds two quarts of capacity, and uses Banks FlowThru Fins® for cooling. Unlike stock, it allows the oil pickup tube and pan to drain fully during oil changes.
