iridium plugs - NGK or DENSO?
I'm gonna change the plugs in my IS, figured I'd poll for the best results by users and popular opinion.

I really don't think you can go wrong using either one. Both brands are designed with the utmost quality and are built to the exact specifications for our cars. In the past I've bought NGK because they were more readily available as well as a little cheaper, but I'd sway to the Denso side if I found them cheaper instead. Good luck.

Denso's have a slightly finer wire than the NGK's , 0.6 to 0.8 I believe , so the Denso's might burn slightly better but won't last as long , I think the factory reccomended mileage is less for the Denso's than the NGK's .
Personally I don't use anything but NGK's !!

I've used 'em both. It's really hard to pick one over the other. Both are the best plugs I've used.
However, I just put in Torquemasters (TMs). GS is now like a rocket ship. Unfreakinbelievable.
