01-07 / 11-16 GM 6.6L Duramax Oil Cooler Adapter

Problem: The original equipment oil cooler adapter relies on a metal gasket on the oil cooler that over time is prone to leaking as the cooler flexes.

Fix: The Fleece Performance oil cooler adapter utilizes an integral square cut seal ring on the oil cooler mating surface in place of the leak prone gasket to provide a superior seal. Slotted mounting holes on one end allow for easier installation.



Fits MY 2001-2007 and 2011-2016 Duramax engines
