Gap looks fine - but what do we know? Check it with a proper iridium plug gapping tool. Spark plugs look clean. 2005's shipped with iridium plugs anyway (might even be NGK's... I forget). When you do roll past 100,000 miles on those plugs, go with stock Delco, NGK or Autolite iridiums. Don't hear much about Champions, good or bad.Originally Posted by TLSheff
minus the fact the gap looks WAY too big, Id say they look like they still got life in em... but if your mis-firing or running poorly you may want to consider it.
Stay clear of platinums, our cars don't like em. If your stock get you some good old ACDelcos, if modded consult Blue's post accordingly for the right ones
