do you have any mods at all?
I've done some extensive research in spark plugs, and went to
www.importpoweronline.com and spoke with the owner (everyone calls him IPO on 3si.org)
platinums are actually not liked very well due to the low conductivity of the plugs, and the coppers are much better for spark. I recently (last week) purchased some spark plugs from IPO to go in my car when I get my 120k service done on my car on 6/4/05. Here are the plugs I purchased.
