Bosh Platinums
-
I figured last time i did a tune-up on my car id go with some decent plugs, apparently Bosch Platinums arent that great. So i noticed a rattle in the engine of my Mercedes Before i parked it for the winter, i tried and tried to locate the source, checked the timing chain (a known weak link in the 2.3's), that was good, check clearances, not an issue. For the life of me i couldnt find the cause. this morning i decided to do a tune-up on the car and...... Holy Shit !!! i found the problem, The whole electrode, porcelin and all are gone out of the no2 plug!!! No more 'high quality' Bosh Platinums for me. Uggh i dont want to remove the head, Just because a Fu%^ing cheap ass spark plug, im sure it wasnt nice to the piston and head. I guess at least i have a fallback, a spare engine.

I would like to take this moment, for all youz that dont know, to say:
NEVER UNDER ANY CIRCUMSTANCES USE PLATINUM PLUGS
seriously, that is all, Use standard NGKs or go away
GaryWell, I know they are a "NoNo" In turbo cars, But not everyone knows what you know about them apparently! and ngk's are sitting on my desk right now :icon_shaking:

the scenario you have shown in the picture has nothing to do with the quality of the spark plug- it looks like it was too hot (like you got the wrong ones!) I am not a fan of the bosch plugs either, but this is an application problem, not a part failureI agree with Andy on this one. I don't care what brand they are, I have seen EVERY major brand of spark plug fail in one way or another. (Some NGK's too). I'll lay money that the Platinum on the electrode had absolutely NOTHING to do with the failure of the plug. As to what caused it, that's up for debate but, dont blame "platinum" or "Bosh" for the problem.

Im not sure on gains. But I do recall someone having spark plug issues when boosting the shit out of their cars. I thought it was either Kevin or Burgess. It probably has nothing to do with wether they were platinum, but maybe they can chime in here.I had plug blow out, but that was my mistake. Stock plug gap while running 15+psi

i wasnt saying that it being a platinum plug was the reason it failed, just the fact that platinums fail in general. Also, you guys that bought expensive ass iridium plugs, those suck too, ESPECIALLY in a boosted application, that is as big of a no-no as platinums. Look at what guys making 1500+hp are using, most are standard type plugs for a reason.
