If mounted on a heatsink (ie cool spreader plate) then 15w will probably also be fine.

Or maybe pick up some resistor packs from an OEM car.
Some Mitsu Evo's use them, Toyota MR2 turbo, old Honda Civics and perhaps others

I thought that S8 can control low impedance injectors without any extra resistors. The pinout pdf says 10A Open Collector output.

Yes it can. I've not found it to be 100% reliable, I described my experiences and advice on another thread.
