Yup, plugs and wires are a great start. use the motorcraft plugs and either
Motorcraft, Taylor, or Accel wires for best results. Some of the other
manufacturer's plug shapes are slightly different and some of the plug wire
boots are slightly different in other brands. You may be able to get away
with some of other brands, but these are known to work. You can get the
plugs from autozone for pretty cheap and the wires from
www.summitracing.com<http://www.summitracing.com>for a reasonable
price.
 Let us know if you need any other help.

O2's are about 30-35 bucks each at Autozone.
