difference in size? You talking about the gap in the plug itself? Well that just distance between the electrode and the other part of the plug (can't think of the name, brainfart)
as for a good set of plugs and wires...either NGK plugs and wires or Denso Iridium plugs and wires but they're a lil more expensives
NGK's probably will run you bout 60 bucks
