I have NGK, 1 step colder platinum plugs in my car right now and i was wondering if it would be better to run a copper plug with nitrous. The zex plugs are a nickel-copper combination. What do most of you run on your car and what is best with a high shot of nitrous?

 

never run Platinum on a nitrous application!

run 1 to 2 step colder NGK Irridium or Copper

 

alright the colder copper plugs are being ordered.

 

I'm using ZEX plugs w/ 100shot, so far its doing fine.

 

there was a problem with with zex plugs a while ago when they came out. they were shorter then usual and were melting the exposed threads on the engine block. im pretty sure they've since taken care of that, but you might want to double check.

 

i dont mean to jack the thread, just had a quick question. how do colder plugs effect driving off the bottle?

choppy idle. but it isnt noticable untill you go with something like 3+ ranges colder then stock. i had 2 ranges colder and could barely notice it on cold starts.
