OK--got it! I need to purchase iridium spark plugs instead of the rapid fire. I was wondering though, what is the difference between a regular spark plug and an iridium spark plug? (I know that's probably a dumb question, but I sometimes I have to learn by asking dumb questions).
What's with all the new members buying Bosch plugs lately? Was there a sale or something?
Actually, I think there was a sale lately, but I didn't get in on it. <g> I have three pre-2000 vehicles and have done all kinds of work on them over the last couple years, but only a year-and-a-half ago I had to change spark plugs for the first time in my life. (It was on a Ford E350). Really simple process, of course, but I was clueless on the different types of plugs. Anyway, I went to the local parts store and talked to the guy behind the counter about why some plugs were priced a little higher than others and about which would give the best performance. I walked out with 8 Bosch platinum +4 spark plugs and the impression that they were top-of-the-line for engine performance. That's why I went back looking for the same plugs for my Grand Prix this time. Glad to know a little better now.
Thanks everyone!
