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.

i tried the platinum 4's on my fuel miser.. just like any other plug change (when your plugs have been used for ten years) the car ran a little more smoothly. Nothing special. They foul more visibly, having way more shiny surface area between the spark and air/fuel mixture. I'm switching to NGK's on the next plug change, probably pretty soon. They're just better. And cheaper. NGK's you get what you pay for (less than 2 bucks) and more. better than not getting what you paid for in other plugs. or having one blow apart. hope there's no major damage.

I don't know why you guys think Bosch suck or that platinums are crap. Yes you can get the same power out of a copper vs iridium/platinum plug maybe more idk. All plugs fail and in certain cars copper plugs will fail miserably long before the 100,000 mile service life of a platinum/iridium plug, try within 3,000 miles. I ran Bosch platinums in my 302 for 10k and had 0 problems. They were completely usable when I pulled them, and would have if they fit my new heads. I ask you this do any of the OEM's claiming a 100,000 mile 1st tuneup use copper plugs, if copper was so great why bother with paltinum/iridium in the first place? By all means if you have nothing better to do than change your plugs every year get copper ones. However if you're not building huge power and don't want the hassle of changing them all the time, platinum/iridium is the way to go especially if you have a DIS system.

id rather spend the 20 minutes every 8000 miles or so to change my plugs, especially after this, and i wont go back to these rediculosly overpriced things, a lot of people are right NGK is a very good plug, i have used them in snomobiles, atv's, motorcycles, and lawnmowers, they always work great. I just thought that this is not a racer or a beater, this is my weekend toy, platnums may be the way to go, apparently not for the price. I have never seen standard plugs fail in this way before, i have seen the gaps, or bridges (whatever you want to call them) missing before, usually in snowmobiles from shrapnel lol :icon_scratch:
