oh no not much to make an acceleration difference. The aluminum one is meant to hold up better and if anythign keep your car running a bit cooler but yeah nothing with acceleration. if what you want is weight reduction think about removing all your seats except the driver seat. and removing the sound reduction crap they put under the rug....but yeah an aluminum radiator will stand up better to heat and wont break like the plastic stock ones do and it doe keep your car running a bit cooler
