Your best bet is to go to the dealer....i have had the best luck with that. If not well get NGK plugs and wires at least. I got my plug wires(ngk blue's) and my cap and rotor from www.nopionline.com and my plugs form nissan. You can get the fuel filter from any parts store. I have heard stuff about getting one(fuel filter) for a 300zx and putting on your car, but IDK. you can go any where for your air filter as well.
Cap&Rotor: parts store brand(i recomend the dealer)
Air Filter: Parts Store
Fuel Filter: Parts Store
