hey all - i might be joining the fold soon with a 2002 black impreza wrx, so i was curious - what are something i can have replaced/worked on/upgraded if i decide to purchase? im talking things like spark plugs, spark plug wires, air filters (K&N) - simple stuff. looking for anything in that realm.
also, what is a good synthetic oil/filter to use? are royal purple products as good in scooby's as they were for my mustang?
links would be great as well!
