What spark plugs shoud i run in my 87 iroc with a L98?

 

i got no v8 but i like the single electrode platinums because they can still be gapped

 

I use AC Delco's

 

ac delco is a good stock replacement but there is a few other companies that make higher end spark plugs but they are roughly 5 times more expensive if not more expensive then that.

 

Just a simple single electrode plug is "best bang for the buck". Either copper or platinum, depending on how long you want them to go between replacement. All those designer plugs like splitfire, rapidfire, and +4 don't make a difference. They just use up money you could put into something that will make more power.

 

Agreed, just because you have 2+ electrodes on your plug doesnt mean you will get mulitple sparks. The spark is going to take the path of least resistance.

I think i remember hearing about someone fileing a lawsuit against one of those companys for false advertising a few years back.
