The power draw worst case for these would be 10.8 Amps for both ( 5.4 A each side ).
The fuse for each side low beam is 10 A, and the high beam is both on a single 20 A.
While the fuse might take the additional load over stock, and the wiring might take the additional 1.6 Amp load fine, the issue here becomes the drop over the factory wiring. If you install an external harness ( dfuser.com has one for 9008 / H13 bulbs ), you will get less drop, and the light output to from the bulbs will be greater.
I 1st did this on my ZG-1000, then I did it on my truck. The only thing I changed on the dfuser product was I removed the fusable link, and installed an ATC fuse maxi fuse holder for the power ( easier to get if I happen to blow it ).
Might be worth spending the money on the harness if you are spending the money on the aftermarket bulbs.
