I don't think his mods justify a 1 step colder plug. I would just go with the NGK OEM plugs. They are fine for your current mods.

copper NGK's - some people swear the spark is better (I have no proof of this) $2 each bummer is you have to replace em more often than the iridiums or platinums, but I like taking my car apart, so copper gives me something to do!!!

I use NGK coppers on mine, one step colder too. I switched from Autolite platinums that were not 1 step colder and these NGK's make the acceleration feel ever-so-slightly smoother... I think. Changing spark plugs didn't fix my CEL's though, I still have a constant CEL and if I reset it then it just comes back on a few weeks later for seemingly no reason.
