Nitrous Oxide, Spark Plugs? Options

[JoKeRkId613]

i have a friend with nitrous(150shot). i remember a while back us talking about nos and i told him i was thinking of doing that. the ting is that i have bosch platinum +4 spark plugs and he said that nitrous won't work well with platinum core plugs. i know that zex has "hyperformance plugs" with a copper core. i was thinking of getting ngk's tho because i dont think the zex brand will be all that well. i had two questions: is it true that my bosch plugs wont work with the nitrous? and what is the best spark plugs to us on my automatic 94 ST that will also work well with nitrous? thanks!

As far as knowledge, i've learned the hard way running nitrous on carbed cars, in your situation I would be careful at 50, the 7A isn't exactly a beast no matter how good it runs at 196,000. 50 is possible but you'll probably experience bearing wear soon and there's no telling with the drivetrain. You should look into staging with a 25 shot for take off and a 50 for top end. It's definitly a good choice just make sure you do everything right or you'll blow your motor. Yeah Denso's should run fine and as nik said a step hotter wont hurt but for that low of a shot it shouldn't matter much. I'm really considering spraying my 5S, i'm looking at the NOS direct port for a nice kick. Also what kit were you considering, I would recommend a Wet kit due to the small duty cycle of the 7A fuel injecters, it helps to have that extra fuel just in case. Remember as I said before start rich, better to waste fuel and foul plugs than buy another motor or rebuild the bottom end.

EDIT: running a hotter plug helps prevent fouling, but if it's to hot it will lead to detonation. Alright i'm out for the evening, i'll check back in the morning.
