I replaced my plugs a month ago and talking to the
Western Auto sales man, their data base showed that
the proper Bosch Plug was the Bosch Platin Plug #4217.
These looked much different than plugs I have bought
in the past in that the tip had a white coating rather
than just the exposed metal. I have always trusted this
store so I bought them. The 6 has been running fine
and I will pull one or two of the plugs in another week
or so to see how they look.
Anyone else run these?
