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.
