i am going to do it this weekend for my car..it looks really easy...if you look on the left and ride side of where the intake manifold ends, down below you will see 2 black square looking boxes....there is a screw there which secures a "coil plug", remove that and just unscrew the spark plug which you will see...for the left side remove the washer bottle and the battery or even just the battery (the two spark plugs are right there) and for the right side just remove the air box and they are right there (alil tighter but easily accessible)...if you have any questions refer to this link :

How about on a 2000 impreza 2.5 RS?

 

it was easy to install, just alil cramped on the drivers side, but very simple...although i still have a cel...swapped out my spark plugs but not sure whether my car needs retuning or what?? sorta confused as to how i can still be misfiring...spark plug wires?? how did yours go?

 

DanyoCantDrift, were you misfiring before the plug change?

make sure the coil packs are on securely. if they are and everything is ok there, maybe you have a coil pack going bad.

 

you think it might be my coilpack, cuz yeah i was misfiring before i did the change....also shiv at vishnu mentioned i might be misfiring after he installed xede on my car, but i am not sure what is going on? how much are replacements and is it easy to replace?

 

don't forget anti seize on the plug threads.
