I am running a 55 shot of nitrous, and i was wondering what kind of spark plug gapping i should have. Right now i am running NGK iridium spark plugs, but when i hit the nitrous my car sputters, kind of like the nitrous is putting the spark out or something...Any help would be appreciated. Thank you

i am running a dry kit....i am not sure if it is detonation, doesnt really feel like it. i like the nitrous though when it isnt doing this to my car lol.



you are running lean and what you are feeling is probably timing retard do to detonation. if you keep using the nitrous, its only a matter of time before the motor cant take it anymore.

take out your sparkplugs and take pics of them to post here. their color will tell you exactly whats going on.
