how much power would those two items an to a 2005 sti if installed? sorry for the question, but i did a search and found nothing? thanks for any help. oh, would the perrin crank pulley help any?

 

well my first question to you would be....Tuned? or Untuned?

Untuned id say you'd make about 225whp, but no need for the intake...do a research on them for our cars, not neccessary (at least not in your instant)

Tuned (Dyno not basemapped) id say maby 235whp maby little more little less, pends are where and who tunes your car. I notice your in Florida, not sure of any shops that tune in your area, but im sure there are some.
