Think you will find the standard air box with a green panel filter is pretty good my STI along with other mods is runnin around the350 bhp mark if i was you i put the money towards some headers (thats if you still have the standard headers )and up pipe Tracktive Solutions carried out the work on mine made a massive difference to the throttle responce and the Turbo spools a lot earlyer and faster But you would have to have your ecu tweeked to get the best from any further engine mods.
