Platinum Spark Plugs?
AC-Delco 41-932 plugs are the perfect plugs for the stock or lightly modded L67. They are the same as stock plugs only 1 heat range cooler. I think the number was changed a little while ago but if you give that number to Autozone or Advance or whatever they should be able to give you the correct plug. These plugs work wonders.

Never buy Bosch. They burned up in my Bonny after 3 week of use, and caused my caravan to almost stop running completely after 6 months of use. Worse plug I have ever used. I now use AC Delco Rapidfires, really good plugs!!
