Hey, I just wrote up a how-to about tuning up your aveo from stock plugs. Like you I waited way to long (81k). I used new wires and autolite platinum plugs and they made a noticeable difference in acceleration and in startup. like others have said, if you want to go with copper plugs, you just have to change them out more often. but the better metal plugs like platinum or iridium will last longer, which for you and I is a good thing since we like to procrastinate! lol. get them things changed and youll see what I mean.
