spark plug，battery and air filter 通常多长时间需要更换？我的车是93年的Honda accord,如果要换，应选什么牌子或型号？今天去Canada Tire and Wal-Mart，there are too many, I don't know which one I should choose? Thanks.

spark plug，
I suggest you to go NGK or Bosch platinum. NGK should be your first choice, which is for most Japs cars. Don't use those cheap Champion or AC Delo(.99c when on special), too cheap, most for American car.

battery
Don;t change until it dead. Use those with CCA at least 640.

and air filter
Visually check, if oily or gunky with dust, change it. Any brand is OK.
