Thumbs up 10,000 Supercharged Miles on the Spark Plugs
I pulled the four on the driver's side (5-8) and they all looked like this.

Looks a bit sooty - maybe a bit rich, but that would be preferred to too lean. The plugs on my 89 (NA) are cleaner and tan.

I think that looks like a good burn with a slightly rich safety margin. thank God the plugs are looking so good. Its hideous seeing detonated cylender plugs, they look like a truck ran over them a few times. What are you running, NGK?

These are Bosch, at the OEM heat range specified for the car.
