I do not have this item, should be less than a 1-hour installation with the right tools. The cooling fins on this cover should help to keep high temperatures under control and increase differential life to avoid a costly failure. It would depend mostly on how hard you drive your "G". Using a simple temperature gauge on the same road course before and after the housing change should so any temp change results.
