it could, most turbo guys use it to clean up the top of their engine, allow them to attach extra injectors or sensors and run a bigger TB. in addition to that it keeps the air cooler, and probably flows a bit better.
general consensus here is that if youve got a stock NA, there isnt much that can be done to the intake (designed by toyota engineers for countless hours) thatll improve it. we've even questioned fooling with the ACIS, but that wouldnt do much good either.
