I have Denso Iridiums and they work great. Would be even better if I was boosted.

Well, 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:

[KA-T_240]

I run the $1.77 plugs(NGK) in my car wiht out problems. I also put them in my jeep.......

[bubba]

Lol, I could have told u they were junk. We sell them at work, but most of us refrain from letting people buy the bosch plugs.

[dynotune]

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 failure

[kylush]

Bosch suck, i run NGK Iridiums and they work great!

[RidinRails]

i use denso iridums and they're great for $12 a piece ha

I got mine new-in-box off of eBay for $48 (for 6 plugs). You do get what you pay for.

I 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.

[KA-T_240]

anyone have any proven gains from there expensive ass plugs?

[weshole]

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 really dont think it is a heat issue, these also cross reference to the engine in the books, i have seen what lean conditions do to plugs and the remaining plugs have no sign of metal blowing away and are showing the nice tan or brownish coloring. also i have heard from other people about this problem with platinums in general before, but usually in turbo cars. i will agree that it may not necisarily be the fact that it is a platinum, but personally i beleive that the electrode/porcelain was defective. i have seen the bridges fall off of plugs before but for the whole electrode to fall out clear up to the metal casing isnide to me is odd.

Based from my knowledge, I would be inclined to agree.

I had plug blow out, but that was my mistake. Stock plug gap while running 15+psi

[Afsil80]

NGK FTW.

It's what I run in my DD.

[Grr]

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.

Last year when I put the turbos on Andy had me change the plugs at the same time. I never would of guessed the plugs would have given us a gain of 400+ hp:rolleyes:

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.
