Why add a Secondary (Auxiliary) Oil Cooler?
Cooler running engines produce more power, last longer, & are more comfortable to ride.
The factory Low-Mount Oil Cooler does provide cooling benefit. But it is not nearly as much in the wind, nor nearly as effective an oil cooler as this oil cooler.
In our tests with the Auxiliary Oil Cooler, oil temperatures were consistently 17-22 degrees cooler, and head temperatures were 15-20 degrees cooler.
