people running them, which ones are they? i went in the oreillys and asked for NGK TR6's and they said well do u have a number for the plug and if i know if i want iridium ix's or some other one.

thanks
 


so 103s should be ran with a lets say 3.25 and lower pulley and 104s should be ran with 3.8 to 3.4 pulley?
 
So ok so I'm running a 3.4 on it right now. With headers, ported heads, 160 tstat, EWP, gen v, 78mm tb, S2 ic, 65 injectors, racetronix pump, E85, and HS 1.9 rollers. I'm gonna run 104s at what gap? Then put the 3.0 on a little later with 103s, what gap with those?

I always stayed around .055 with gap on plugs, that too high?
 


the only way to know the right gap is to run the car and see if they blow out. if youre lazy like me you just gap them at ~.045 and be done with it.
 
if your gap is too big youll blow out the spark and get misfires. youre supposed to gap them and slowly increase until you get misfires, then close it up a little. it takes a lot of time that i didnt care to take.
 
I had an issue with the people at O'reillys too.. The lady kinda threw a fit when she looked up and said on the computer its supposed to be 606 so I told her to bring both over and compared em. So when you do go in there just tell them what you want and save yourself the hassle.

And I thought the gap was supposed to be .06
