Do NOT use platinum plugs with nitrous, platinum is softer and melts lower, NEVER use platinum plugs actually in any hi performance apps in general. As with anything there are always exceptions. Platinum is also a very poor conductant of electricity, try the NGK Iridium or Denso Iridium.

what really matters is the heat range. It used to say go two steps up on the ZEX website. They've now changed that to use ZEX plugs. This is because each manufacturer has their own heat range. With nitrous you need a hotter plug. Some manufacturers go up with heat, some go down in numbering with heat
our cars come with NGK 7 (or that's what I use for my nitrous setup, i can't remember it's been a while). You want higher then that with nitrous. Heat range tells you how hot the plug can handle.

our cars come with a heat range of 5
you run 7 when you run nitrous
i just use regular resistor spark plugs and just change them often (bke7e-11 for nitrous using ngk)

great reference chart, adding this to my this to my info pics album
and yeah 7 is steps colder for us, best for nitrous and boost
i went to the crappy "Zone" and they did not have them in stock, best bet is trying Summit
