http://www.frsport.com/NGK-Iridium-IX-S ... _3102.html They have the heat ranges right there in a drop down. Use a cold plug to avoid pre-ignition. I'd run a 7 or 8, the cooler the plug the worse it runs in cold weather and they are less efficient for idle, but they are a must for boost. I use Iridiums, have since 99.

Here's a list of NGK plugs with part numbers and prices from NGK's site. See where it says, BKR5EIX-11 for the iridiums? Change the 5 to a 7 or 8 for a colder plug. I didn't see the coppers listed.

NGK - KA24DE - 240SX Part Numbers.

Here's an awesome spark plug cross reference.
