Which iridium plugs are better - NGK or HKS
Which of these brands of iridium plugs, if either, are superior in the G35 and why?
Please leave price out of the equation.
I'm looking for replies from those who have specific evidence or knowledge based on experience rather than brand loyalty responses.

Well, I switched from Denso iridium with about 40K miles to HKS iridium about the same time I installed the HKS DLI II ignition amp.
My impression is that gas mileage is about the same but the car feels a little stonger. But I can't be certain so don't put much credibility in this.
Unfortunately, I'm about 100 miles from the nearest dyno, so test results won't be soon coming.
