Is the one on the lower right from cylinder #1?

Did add some kind of fuel additive?

I'm not sure which spark plugs belong to which cylinder because i accidentally mixed it up when i was taking the picture. These spark plugs went through about 25000 stock mile, 1000 with JR supercharger and about 3000 with the greddy turbo kit. Octane booster was used in couple tanks of gas, but not very often. How does these plugs look? lean? or normal? I just switch to ngk Bkr7e gapped at .032 and the car seems to be running not as good as before. Since the change, i also see more activity on the j&s knock display? Aren't colder spark plugs suppose help lower the chances of detonation? Should i switch back to my stock plugs. I'm using a stock ignition for now, but a msd6btm will be added soon.

Got to NGk spark plug web site.

Any ideas why switching from stock plugs to one range colder spark plugs would cause more detonation according to the J&S knock sensor. Now with the new Bkr7e, the j&s would show major detonation every time i would step on the gas, and this started right when i changed the plugs. Any ideas?
