75 wet shot ?plugs?

[davergt]

Planning on doin 75 shot.
stock spark plugs are ok, right?

You really should go one step down and get copper plugs.

I run Autolite 103s, cheap and effective.

u need a 100 shot... 75 wasnt enough to make me happy and i have a non pi car 208 rwhp!! night and day between 75-100 shot

1 step colder copper plugs for 75 shot and 2 steps colder with the 100 shot.

sorry but, what would 1 step colder mean???
i asked the guy at parts store and told me i was talking another language. he had no idea what i was saying.
which plugs would you guys recommend???

 

[davergt]

does going colder affect daily performance??

get a heat range colder plug... the colder the heatrange the less heat the plug holds in... generally they change the amount of porcelain(sp?) between the center peice and the outer shell... the reason you want a plug to stay hot is so that it burns off deposits from unburned fuel and the like but when you are spraying nitrous you are creating a MUCH hotter burn and the plugs need to be able to get rid of that extra heat as to not cause pre-ignition... if you goto Advance Auto or Autozone tell them that you want Autolite 103's or whatever the guy farther up the thread said... generally if a stock plug is a 104 then a step colder will be 103... NGK is the only brand i know of that goes th OTHER way
