I'd like to see one bit of proof that they help. Just being skeptic. I'm not saying they might not gain you a little, but if you want 12 hp, run another psi of boost. I would love to see any before and after dyno info though. Stick with stock, as any of the "big" hp Protege's out right now have all done so stock, so why bother, save the cash.
