Welcome to AF. Stay with the AC Platinums or Iridiums.

thanx for your advice man!!! i also have water spots on the right side of my car and they won't come off with just water and soap can you recommend something?

Are you sure the misfire is due to a bad plug? If your wires are original, I would change them as well.
Try a good quality wax to remove the water spots.

yeah because i haven't changed my plugs in the longest time... are you sure the water spots will come off with just waxing the car??

Normally a light buffing is required to get these out.
