Spark plugs ???

Any thoughts on what's a good plug to run in a '88 TPI 5.7 IROC ???

thinking of mabie NGK line,, just wondering what everybody's using.

car and ignition systems all stock no plans on any Mods, i like stock....

AC Delco.

I hear NGKs are great plugs lots of people run them in their camaros. I have Bosch platnum +4s in mine and I don't mind them at all, lots of people won't run them in their cars. not really sure why.

I use Bosch platnums in my 89...My family likes Bosch...
I like stock too :icon16:

Any other thoughts??????

Well ive heard that you get the best out of AC Delco, NGKs are pretty good but they vary from car to car. I wouldnt use those platinum plugs or iridum or whatever else they have because it doesnt give one big spark but 4 small ones, get these if you want to get a big more MPG but ive heard it kills horsepower a bit.

Yea i heard somthing like that too....

I'm kinda leaning to regular AC or NGK...:banghead:

Bosch = random misfire. They just aren't what they used to be.

NGK, have heard good things as a supplement to OEM.

AcDelco =OEM and in my opinion after dealing with these ignition systems for for over well 12 years are the most reliable, for me it's Ac the whole way for every part of the system.

Yup i agree

ditto on NGK or ACdelco. Cant go wrong with either of them.

another vote for ac delco. i would never use bosch, i've seen them break apart too often.

So are you guys voting for the regular plugs or Plats??????

With how hot these mtoors run, regular 100%.

AC Delco Rapidfire's are the way to go.

AC Delco, Starts the engine on the first try XD

AC Delco Rapidfire's are the way to go.

Funny...i actually have the rapids in ther now...

I wasn't shure if there was somthing better or what everybody was using...

Well, according to what ive used.. which was AC Delco plugs at first, and in all honesty I have no idea how my Camaro ran or started up with those things because they were literally black they also looked like they came with the camaro out of the factory :lol: so it shows how they last, then I used some NGKs and now im back with Delcos and i'll say that yeah with the AC Delcos my maro does respond a bit better and I can actually feel the difference even though its small, compared to the NGKs.. but im not bad mouthing the NGKs, but I do feel that AC Delcos are better on a maro atleast.

So Rally you using plain R45ts then??????
