Good buy, stick w/NGK plugs, like your car has and replace the wires w/what it should have. Hinda/Acura ignition is a good set-up and no need for bigger wires or platinum plugs. The cap and rotor most likely need to be changed out. A fram filter is good to go. GSR is manual only, always has been since it is raced inspired (for it's time) it was said that it would be an isult to the motor to be attached to an automatic tranny. Your timing belt is good until 100k, at which point all belts and waterpump must be replaced. An intake (replaces your stock airbox) and exhaust should do you justice since you really don't want to go all out. But let me warn you, once you start you want more, and before you know it you'll be knee deep in the shit, you'll need boots, so buy some now if you don't have any.
