2003...2004 what's the difference?

I'm sure this question has been adressed here before, but I can't find it.

I own a 2004 corolla S and I would like to know what major differences there are from the 2003?

I saw somewhere that something about the fuel line is different. I'm relatively new here and I

don't want to blow up my car doing major mods that were meant for an '03.

Anyone's help would be appreciated.

Probably only cosmetic changes, if any. I believe models were carried over w/o any changes.

I think you might of been confused about the 'fuel line'. I think its actually the fuel maping in the computer of the car that is diffrent. Thats why the superchargers wouldnt work on the 04's untill they released a newer piggyback computer for the 04's. Other then the little fuel mapping diffrence, i think there pretty much the same.

aha :!: the fuel mapping. That's what I remember seeing. Thanks
