Your STi comes with the expensive paper filter. IMO, that's probably the best filter option for the car. It flows well while still filtering out all the little grit that sandblasts your turbine otherwise. I plan to use them when I do my conversion.
The JDM pink springs are definitely better than Eibachs. Many people believe the STi struts are actually suited best to those springs. Because of that, I personally don't think coilovers are the first option on a street-driven STi.
