GM Rapidfire Spark Plugs - Anyone Tried Them?

What is the best (sure to get 10 answers here) replacement spark plug for a stock 2002 SS?

Let the fireworks begin...

NGK TR55.

NGK TR6 if you use nitrous.

i would use the delco iridium plugs part no. 41-985 (12571164)these will work great and last a very long time.,

[Wesman]

AC Delco plugs are great. I think they are the best for GM vehicles in general.

Never used Iridium plugs though, perhaps someone on here has some experience that they can share...

[YoMommasTA]

i'm using them for over a year

[Silverbird01]

NGK TR-55.
I tried Rapidfire plugs once...................didn't like them. Put the NGK's back in and everything is good again!

I use Rapidfires with good results in my Chevy truck with a cast iron smallblock engine,but it's only AC Delco iridiums for my LS1 Corvette.

I've searched poll after poll and threads and these are definaly the most recommended from what I've read.

I do not post here much, I was unaware. My apoligies to keliente.
I'll have to watch my gender posts from now on.

I run NGK TR55's in my H/C 402ci. Gapped at .045".

I will run either those or Delco plugs. Nothing else.

NGK TR-55 I just had these put in two days ago. Well worth it. I had the car on the Dyno with the original (AC Delco) and then after with the TR-55 Engine seemed to run better on the TR-55 (Of course could have been the other mods too!!!!!)

NGK's are great.....but I have to tell ya...after I read an article in GM Highperformance I gave Brisk Sparkplugs a shot and I have to admit they are something! Only problem is they are a little high and it's hard to find them.....Great throttle response with them and they even seemed to outperform the NGK's.......
