I found this nice aluminum radiator from Australia and decided to give it a try :)
It is not a direct fitment for the 8998, as it says it is for the 9904, but works well with a few modifications.
Also saves a decent amount of weight. I should have measured, but the Aluminum is soooooo much lighter.
