I tried many different plugs in my car and found that with my mods the stockers had the best performance.

The stock plugs are gapped to .040 by NGK, the plugs I pulled at 10,000 miles ranged from .037 to .039 gap.

I installed fresh OE plugs gapped to .040 and had hicup issues, so I tried .039 and got a little hicup around 5,000rpm.

So I set another set of OE plugs to .038 and wow smooth as silk and no issues from idle to redline. My car had always had a slight hicup once and awhile and it is now gone also.

 

keep us updated if it comes back, cause mine used to do it all the time and it seemed to be fixed, but very rarely it will come back. the hic-up that is

 

I got question, and hopefully im not high jacking here, but im about to go stage 2, should i be changing the plugs to a different gap, or wait and see until i start getting hicupps?

 

good for you. with the stock plugs and the stage 2 what are you using to measure knock? because your getting some. thats the reason i switched to one range colder. not because the gap or a hickup.

 

you dont always need colder plugs. i ran a 3.4 on my riviera and i had to run .5 step hotter. the colder plugs ran like crap and so did the stock range. and i had a powrtuner

 

Basically, My car runs like a raped ape and the hicup was my only issue. So with that gone I don't think KR is really an issue.

And DrkknightSS99 I wouldn't really worry about it until you have an issue.

My hicup was present even when 100% stock and Stage 2 made it a little worse yet. No it is completely gone.
