Spark Plugs For Nitrous

[SliverStang]

Im going to attempt to install my NOSzle kit today. What spark plugs do I need for the 125 Shot. And also what gap do I need to set them at?

Id also like to know as i've been considering spraying until i can save enough money for a supercharger. 125 shot seems kinda alot are you sure thats going to be safe? How much was the entire Nozzle kit & where did you get it from?

With a 125hp shot NOSzle kit I would run any two step colder plugs.

NGK TR-6's. These are NGK's copper racing plug.

I'm running Autolite 103s, but that's on a 75 and 100 shot. If you want to go over a hundred, or just be safer, go Autolite or NGK 2 steps colder

I ran autolite AR94's(2 steps colder) gapped at .035 when i had my noszle kit, worked great!

Do you have to run different plugs when using nitrous? I am about to buy a kit within a month and i didnt think anything about plugs? How come the kits doesnt tell you to buy different plugs?

Actually NX does. In their instructions they tell you to stay AWAY from platnium plugs if you have nitrous. I don't really know why you have to change to copper. Mabye the other companies don't. Good thing is the copper autolites are only a little over $1 each, nice to buy something cheap for a change.

autolite 764s or ngk TR6s for up to 100 shot anything over that BR7EF ngks . autolite 103s might also work , always gap in the .035 range

Silverstang with your 125hp NOSzle kit don't run Autolite
764's because they are the stock heat range and you will blow up your
engine.I would seriously run some plug that is two heat ranges colder
like Autolite AR94's or NGK R5671A-9 and if you are going to run that
125hp shot I say upgrade your intank fuel pump and fuel pump that way
your engine will get the extra fuel needed to be a the safe side! A .35
gap is fine for nitrous use.I say Good Luck.
