The drag strip opens up in a month from this saturday and before i take my 89 iroc (350) out for the first time this season i want to get her set of good spark plugs! I was wondering which type are the best to be run in camaros, i was thinking about bosh platinums.....but i have heard some good things and bad things so if yall could help me out and reccomend some i would appreciate it!!!

Thanks in advance to all who reply!!!

 

The Bosch Platinum Plugs are pretty popular..

What have you heard about them that is bad?

Bosch Platinums work great but don't use them if you are running nitrous.

 

AC Delco

That is all I ever run, and all I would ever recommend. Not a big fan of the Bosch, especially the gimmicky 2 and 4 prong.

i agree, all i ever run is ac delco

 

AC Delcos here also. But I gotta admit I have Accells 276s in the 91 due too headers,needed a shorty plug.

 

I never bother with the platinums. I just use NGK V power plugs and change them once a year.

 

Im running the AC Rapidfires now and they're OK, nothing to get happy about. Next time Im going to use the $1 AC plugs.

 

I run Accel shorty header plugs, they work great but for some reason the tips of them are unscrewable. So you have to be careful you dont let them come off otherwise they wont work. makes changing plugs with heasers on slightly easier

 

Hey DarthIroc,what does your car run? I have a similar combo on my 91. Also are you using the stock chip.

 

Ill send you an e-mail

 

The regular Bosch Platinums work well for me, much better than the ACDelco's did. Don't get the Bosch +4's though, they are worthless pieces of junk.

 

I have had no problems with my bosch platinums. I was all set to try out a set of Denso Irridiums till I saw the price Needless to say I will stick with either the Bosch or AC's

Ac-Delco Rapid Fires... Got the car with bosch in it, didnt notice a problem with em, just rather have what goes with gm... Gr8 Plugs though, the bosch plats dyed when i ran the msd ign.

 

Autolites, my favorite, available in various heat ranges.
I used Boch Platnums on the street w/o problems but under extreme conditions lead to more detenation. I don't believe they dissapate heat well.
I ran Accel, side gapped slightly to improve flame travel, with no problems. (..just filed off some of the ground..) A/C delco's work well enough but wear more rapidly, and I experienced a slight "miss" with the last set I used
My buddy used a set of Champion "Gold-Truck"plugs and it smoothed his idle out, they are a Heavy Duty built plug that should take lots of abuse.
For now I'll stick with the Autolites...
