NGK BR9EVX platinum

Installed the NGK BR9EVX platinum plugs last week. I have an 00 ZL5 so what I don't spend on insurance I spend on gadgets :). I did not think they would make any difference but they were a nice crispy mid range wake up call for my sled. Has any one tried these? Nice, noticeable crisper throttle response with these plugs. Switched back to the BR9EYA's just to be sure and the difference was consistent.

I'm running a 00 ZR500 + (711) this year and am using the evx plugs only minimal cost increase but when you want the thing to run at it's best use the best.
Good luck and good sledding.
