Default Spark plug degree question

ok
I have no clue about spark plug temperature... as you can see with my dumbass frying 3 plugs

Im going to be riding around the 200-240whp area
What degree plugs should i use?
keep in mind i have a 10lb bottle in the trunk that im addicted to
I NEED MORE NAWZZZZZ!
my final out put is in the 275-315WHP under nitrous and im expecting torque to reach the 350 mark.

You guys think the zex plugs can handle that?
Im going to have new pistons so the last thing i want is ring damage on my new pistons

I currently run around in my zex plugs... nitrous loves those plugs
havent even dented them
lol

hey, i need to do a spark plug change soon. i plan to go nitrous by the end of the year, are the zex plugs safe to be installed in an N/A car, temporarily? or will it throw something out of balance?

They run way different than normal ones (I initially had Denso Iridum) my idle became a tiny bit rougher but they run great with nitrous.

I too am addicted to the nitrous. I recommend changing the plugs frequently. You don't have to use the expensive zex plugs. I'm using NGK V-power (BKR6E). The recommended model is BKR5E for stock engines. The higher the number, the colder the plug. So it depends on your applicatoin. It runs about 6-7 bucks for a set and I change the plugs each time I change the oil.

ok im familiar with the numbers.... im really curious though on WHICH number should i go to once im putting down 220-320WHP
is it 3 degrees colder? 4? 5?
will the zex plugs still be fine?

BTW... just for your info
i fried 3 plugs NGK vpower that were 1 degree colder... like the ones your using (na 95 eclipse plugs)

be careful
i hope your not running a 75 shot

btw... denso iridiums, i believe suck too
be careful.... i think someone reported a loss in horsepower with those
next time just get the zex... better safe than sorry

i currently have the zex... work like a charm

I remember a while back trying to get v-groove 2 steps colder but NGK does not even make them, so I went with Zex.

i wonder if the ZEX plugs can hold that much power
they are specially designed for nitrous and turbos

but how about nitrous + turbo at mildly insane levels
