Nothing really. They pretty much all look like that.

i thought so too.. supposed to be slightly blackish due to our car runs slightly richer.. mine literally white in color.

when i got my shipment of plugs, i'll post my old one up here....i wonder how it look since it's already in my car for around 1 year.....

and the fuel in my country is really pouring in alot of additive to gain market share...
my last iridium plug end up clogged with white deposits.. .VERY BAD white deposits... now it's the stock plugs in my car.

stay tuned for plug pictures :P

Not mine, but another O2: https://www.rx7club.com/new-member-rx-7-technical-256/o2-sensor-good-bad-895864/

My old one came out white as well. The car never ran race fuel.
