Hi all,
      I noticed seeing a discuddion about Bosche platinum plugs.  The best
plugs I've ever seen believe it or not are the tri-electrode plugs the dealer
sells.  In my dealer days, we'd pull plugs that had a solid 60,000 miles on
them, compare them to new plugs, and besides the light brown coating there
was virtually to electrode eroding at all!!  I tried a set of those
splitfires and had no performance gains or increased fuel economy at all over
the factory plugs ( in my 4KQ )...  Havn't compared them to platinums but I
suspect that there will be no noticable difference...
