Which spark plugs for NITROUS setup?

[trainville]

I recognize the need for a 1 or 2 step colder plug. I'm about ready to install a wet 200 shot (NX)and was wondering what plugs you guys are using? Any other mods I might need to make?

I'm already set up with the Vec 2 to control WOT and RPM window. Thanks,

mine ran best with one step colder but i cant remember which plug number

 

[2001 GTS]

I use autolite 3923s with my 200 shot. They work great!

 

[99 R/T 10]

Use the stock SRT plugs! They are the best out there, RC10ECCs

The RC10's are two steps colder, the RC12's are the stock SRT10 plug. The RC10's still have the extended strap. It would be nice to find a plug that is colder and has a strap somewhere between a standard reach and and extended reach.

Our cars don't like the standard reach due to the combustion chamber design, the plug is already shrouded. When you go to a standard reach, low and mid range response suffers. The NGK FR5-1 is a plug that is the same heat range as the oem plug, but, it has the strap is half-way between extended and normal. The FR5-1 in one range colder might be a good plug.
