Take it to the dealer. Its a hard job. Probably one of the hardest due to its horizontally opposed 4 banger engine.

You need to remove a lot of bolts & disconnect several wires/electrical connectors. Use a spray can of penetrating oil sparingly, as u do not want to break off a rusty bolt or two, like l did last year. Remove whatever is in the way, including the air box & washer reservoir. The WRX has individual coil packs ''on top of'' each spark plug. You will have to remove the bolts holding the coil packs to remove the coils & get to the plugs.

My recommendation:
Replace the plugs with NGK Laser Platinum PFR6G

It is not a hard job. It requires a lot of patience & care. This job is a piece of cake when compared with some VW/Audi engines & older GM V6's. Be careful.some of the bolts will be rusted & can break off easily.
