Bosch Platinum +4's bad for My SS ?
Hi Guys/Gals,
I recently put a set of Bosch Platinum +4 plugs in my 2001 Camaro SS (54,000 miles now). It runs super after putting them in and also putting in a set of Taylor 10.4 MM racing wires. A few weeks later I hear from 1 guy at a local auto parts store that they can possibly cause cylinder wall damage, and a mechanic at another shop told me that I may soon start to see a dramatic decrease in power, as they do not work well in F-Body's for some reason. He said the 4 electrodes at the end of the plug block the air/fuel mixture from reaching the spark. He said his '97 Z-28 took very badly to these plugs and he had to take them out after about 200 miles when he noticed a serious decrease in power. Putting in a different kind of plug fixed the problem.
Does anyone have any info they care to share about these plugs? I would really appreciate it. Thanks.
Tom

From what i've heard, platinum sparkplugs should be one of the first things to replace. Specially if you run a turbo or supercharger. The plantinum on the sparkplugs runs hotter than regular sparkplugs wich you will have a better chance for detonation. I'm trying to do some more researche on this also.

The LS1 isn't high enough compression to worry about the hot platinum causing detonation. You'll be fine

For the record though, I don't have them in my LS1, I went with ngk.

My Bosch's only have about 800 miles on them so If I have any problems in the future I will be sure to post it.

I've put Bosch's in at about 70ish, on 82ish now never had a problem. I know before I put them in my car was running like shit, rough idle and a little hesitation at WOT. After the install and ever since my car runs fine. Maybe I'm the only one. What is it about Bosch that hurts GM cars?

I don't use them because I heard that my brother's wife's cousin's grandfather's best friend's grandson's next door neighbor knew a guy that worked with him said that they were no good.
