How hard is it to change spark plugs in a 2004 chevy malibu?

If its a 3.1 the front plugs are easy. the back 3 are a pain to do. I could go into detail about removing the coils and the plate to make it easier but i would recomend a reputable shop to do this one. If you take it in make sure to tell them you want all the old plugs back. I have seen some techs. only replace the front 3 and leave the back 3 cause they are to hard and figure noone will know untill next time they are replaced.How hard is it to change spark plugs in a 2004 chevy malibu?
if its a 4 cylinder it shouldnt be that hard, if its a V6 then its a pain sense the plugs are on the side, and you might need to take alot of stuff off to get to them
