Answer 1

Changing plugs won't help; use the manufacturer's recommended units.  It is possible that a tune-up, and maybe replacing plug wiring, would be helpful, but it is very easy to oversell these services, so consult a trustworthy dealer.  Modern automobiles are almost entirely under computer control, so aftermarket modifications (which the computer won't understand) are unlikely to be helpful.

Answer 2

buy some Denso or Ngk plugs, they work best on Import cars.

give your car a complete tune up.

make sure no "engine light" is on.

Answer 3

Plugs wont hurt but likely wont help as much as a complete tune up.

Answer 4

You can usally look under the hood are on the radiator cover and they will have a sticker telling you what plugs and the setting to use .You should go ahead and replace the fuel filter & the plug wire's a long with a new rotor & distbutor cap , be sure to check your air filter & pcv value ,while your at it , that should put you back in good shape.
