what's the best width to gap your plugs using nitrous?also what's the best brand to run with nitrous?right now i have autolite double platinums with a gap of .054.i've read that a gap of .032 to.036 is preferred plus a plug with a short electrode is better to use.i'm finishing up installing a zex wet 55-75hp kit and i know i'll need to check the plugs after my first use of the juice to see if i'm running lean or rich.

I have been using autolite 103's with a 55 shot of zex and have been doing fine but I just got a set of Iridiums for free that I would like to try out. Dont remember what gap I used on the 103's.

i e-mailed zex and ask them about plugs and gap.they replied that what i had was fine but suggested a .050 gap

Do not use dp plugs. You will blow the tips off. I would use autolite 103 and gap them around .040

good luck
