i have been researching it a bit, and havent came to a definate conclusion. I am running a rebuilt with all oem parts h22 in my accord, and i just got my nx wet efi honda kit. Now i was thinking about it, i dont think i would need colder plugs because i am spraying fuel at the same time as the n02. As i understand it, the reason for a colder plug, was to reduce detionation caused by the increased heat in the motor when the n02 is used without fuel. I am going to be using the 75 and 100 shot nozzels. If somebody could clarify this for me, i would really appriciate it.

 

come on peoples, somebodys got to help me out

 

Yeah you will need at least 1 step colder plugs, the extra power made produces more heat then standard even with the extra fuel.

 

I run a 75 shot on a B16a. With the research I did, I concluded that I needed to run one step colder on the plugs and retard timing 2 degrees (to be conservative). I have run about 20 bottles through my motor and it is still very happy. (Stock B16a 10.2:1 compression)

 

cool, thx guys, i just ordered 1 step colder ngk iridium plugs for 6 bux a piece, and i am just going to throw my car on the dyno to tune the timing. I appriciate the responces
