First plug change.

Those plugs are cold - barely burned into the first thread
IMO they look lean for a street application - I like to see a little more color for a safe all conditions driving.
I cant even see a timing indicator on the ground strap. What's up with that?
Any indication of detonation when driving?


It’s pump gas. They look ok except for transition and WOT.

The difference from left to right can be distribution issues or just a rich condition that will clean up with some tuning.

On pump gas I don’t mind running the heat Mark to the shell.
