After a long hard search I have finally purchased my first subaru, will be collecting Friday! Now it's time to clear the garage for my new baby. Before I collect it will be having an MOT at no extra cost for any work required if any, now the garage have told me they will be doing an oil change but obviously I want filters doing etc. can I do this myself and where is cheapest to buy? I have a 52 plate wrx sti prodrive. Ryan
