Modern unleaded fuel doesn't respect the traditional plug colours regarding state of tune
Baby Sh*t brown for a correctly set mixture doesn't happen anymore...
Yes, it was quite a suprise to me when i took them out.
I'm quite happy now and see no need to change from the NGK's, they work just great.
I only changed the plugs as part of the service I was doing, thought I may as well do it just to be sure.
