I ran Bosch Platinums (regular kind) in my '88 5.0 LX for eight years and 136,000 miles. I loved 'em. I run them in my Cobra now. Personally, I think all those +4, Split Fires, etc. are gimmicks. I change my plugs every 10K miles anyway, whether they need to come out or not. On the other hand, I know people who run plain 'ole Autolite coppers, and they love 'em. Kinda personal preference, I guess.
