I'm going to receive differing views(responses, I hope) on this subject, but I haven't seen much in these forums on which spark plugs operate the best in a our L-98 engines. Presently, I have Bosch Platinum plugs installed for the last 18,000 kms. Any views on this, please?

I used to have bosch platinum 2's in my 86. When i took it into the local corvette shop, he said just to put the standard AC Delcos in, because thats what the engine was designed for. The platinums will carbon up a lot easier. Now if your engine were highly modified i would look into getting some high end plugs....but if stock, $2.50 AC Delocs will be just fine.

carbon up? boy is that true. I used a set in a stinking v6 toyota and they didn't last long at all.
