I was reading the forum again and I saw that most ppl said NOT to use platinum plugs with Nitrious. Is there a reason for that? Right now I'm using twin turbo Z plugs (1 step colder compared to stock) platinums. Everything seems fine, I've been using it for a year now.

 

From the NX Install Instructions:

In stock engine applications and street usage the spark plugs should be at least 2 steps colder than stock. Do not use platinum tip, extended tip or any plug with multiple ground straps or split ground straps. When in doubt about heat range always go one step colder. A spark plug that is to “Hot” will cause detonation, burned plugs, poor performance, and engine damage. In competition
engines always use the coldest plug available.

 

i used , believe it or not plat plus 4 sparkplugs for two yrs with 75 shot dry.. never one problem. i finally went copper one step after reading that its no good for the car, oops.. i guess i just got lucky..

Same here, did you notice any better performance with the Copper plugs? I just switched mines out yesterday but haven't had the time to try it yet with Nitrious

 

no it doesn't feel better than the plus 4's.. i think its just safer.
i have won some serious races with those plugs. i just switched over
about 2 months ago because i have increased my hp to some serious levels, but if i had it my way, plats all the way....
