If you have a stock mounted radiator, the ast helps get all the air bubbles out. If you have an upright radiator, the ast still helps a little, but the key is to properly bleed out the system. Some say mazda put a lot more R & D into it then us, but I have been running no ast and it's been doing perfectly fine, so have other people on here.
