As far as i know they will not. Unless this is different in your location. The 02-03 has the round (bug eye lights) headlights, the 04-05 have kinda blob shaped headlights (round with a flare at the outer edges called peanut eye lights) and the 06-07 have a very sleek look (awk eye lights). As far as I am aware this is the same world wide and there headlights are the same as I just listed for all Impreza models (base, WRX, STI, etc.) Each of those year ranges recieved slightly different tail light treatments as well so the rear bumpers are kind of year specific too. You can take the 02-03 STI bumpers and put them on your car fairly easily.
