Re: What you think of my plugs?
first pic, Dave is right about the brown ring.
second looks like it's burning a little oil to me too.
last pic does look a little lean,. but modern fuels typically don't give much color on the porcelain.
Dave, I'm not up on the term "pre-ignition fouling", what is that?
And yes again on the pics. Best plug pics I've seen in many moons.
