Bosch Platinum +4's bad for My SS ?

[NastySS]

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

thanks for the reasoning, it helps us understand why you give the answer you give. Without any personal reasoning behind an answer I tend to think that someone "heard something somewhere" and wants to look like the smart guy and jump in with an answer

I put +4s in my 97 at 101,000. at 178,000ish they were finally changed again when the opti went out and everything got replaced at the same time. Never had trouble with them in my personal experiences. this porcelin center coming apart is new news to me, I'd like to see if I can find out more.

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

[dkishton1486]

They make our cars and all GM cars run like shit. They are worthless and I just dont recommend puttng them in at all

WHY. what's wrong with them, they have to do something to make all gm cars run like shit. whats so perfectly wrong with them that they target gm cars? that's some precision shittiness by bosch to target specific makes of cars like that. you havn't given me a reason why yet, you have merely given a vague opinion. I'm not trying to be a jerk, but without reasoning behind what you say it is nothing more than an opinion, and your opinion only means you think they're shitty, it doesn't mean they are actually shitty

our 88 TA started missing after we installed a set of bosch plats,i started pulling the plugs out looking for a problem.one plug had all the center porcelin missing,just the electrode standing there alone.i did a google search about it,i found many others had the same thing happen,even found out that if you send the bad plug into bosch they will send you a comp set of plugs.i think i'll use another brand

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.

[speedaddict]

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?

[GatorSS]

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.

[junkman]

I put a set of +4's in my 88 GTA at 100k and when I got rid of the car at 110k it still ran great

[sgt0704]

i had the +2 on my thirdgen for a while. and i had no problems.
