I use regular Bosch Plats[and yes, they are plat!] all the time, in everything I can get them for.. put em on a spark comparator [or a car that has points you can 'pop' to observe the spark] and you'l see why..
Precise spark in the same place every time[no dancing]
I pay about 1.50 @ for em..
No probs here..

I'm just saying "have you considered?"
If you are satisfied with them, by all means don't switch.
Its just that there must be SOME reason that many have experienced problems with them.
I have yet to hear any complaints about NGKs. I have heard that the stock Delcos are pretty shot after around 60K rather than the advertized 100K.
I believe the center electrodes on the NGKs have more plat on them. JMHO

explain to me if you can why the bosch products gives many people on here problems, is there a flaw in the spark plug design, like i said maybe im one of the lucky ones but never had a problem with mine, going on 2 years with mine in

im glad to hear that, you know we are outnumbered here, if a plug gives out a bigger spark how can that be a bad thing?

They last 'forever'[with no gap change] unless fouled..
1997rblckSS.. expensive?Reg Bosch Plats are under 2 bux @..
You must have 'Plus 4's' which I think overrated/overpriced...
Why 4 grounds? [ spark'll only go to the one that offers least resistance to flow...]

a spark is a spark IMO... , ..oh and before NGKT55R's I had Champion plugs for about 4000miles...all good plugs IMO

Good to see you postin Babba.Since I took some of your advice 5 years ago(well I,m still on the non plats),I am thrilled with the NGK's.Some members have not realized the full potential of this colder running plug,and how it makes the car pull and pull like no tomorrow all the way to the rev limiter faster than anything.If you havn't tried the NGK plug,please try it at least once,you won't be sorry.My02

I'm another one of the folks running regular Bosch plat's - about 10k miles so far. No problems (like a missing puck after 5k miles with those POS AC Delco's I had), less than $2 each, I'm pretty happy them.

Ive personally observed independant tests on this subject.
And for stock applications I reccomend stock plugs.
GM went through all of that trouble to design a plug that would have the exact heat range length and size of spark that the LT-1 would perform best with. Why would you throw all of that out the window and risk it all on a guess?

I've been using Bosch Platinums and I haven't had a problem yet...I'm curious as to what sort of problems people have been having. Unfortunately the sad fact is 90% if plug failures result from operator error (misgapped, not installed right or tight, etc)

what compression ratio are you at? according to your sig, your not using dope vor a blower, so if you're at less than 11.25:1, you should be good with the stock ac delco plug. these guys using tearing up ac delcos in 5k miles have very high combustion chamber pressures, and that can blow the platinum tips off if they get too hot(preignition or detonation). but if you have close to stock compression ratio with no power adders, the ac delcos will be fine.

Just an FYI - I had the pucks come off within 5k miles when I had just a CAI and a cat back. A friend of mine here had the same thing happen to his 97 with a 383/stock plugs. That particular bug seems to bite regardless the application.. there are plenty of others on this site who've mentioned experiencing the same problem.
As for the gapping, really, come on. I'm not trying to be a jerk, but if the simple process of gapping a plug can ruin it, exactly how good is the design to begin with? I've never run into any issue remotely close to this with any other type of plug.
Hey, engineers have designed all kinds of stuff through out history that has wound up on the junk pile. Just because it came from them doesn't mean it's perfect.
