Spark Plug Reading!

Hey all..hope you all enjoyed your thanks giving.

Sorry to have like the 1000th plug read thread but i've searched around online for plug readings and the plug i pulled seems to be good let me know what you guys think!

Patriot Performance 500hp crate engine has about 10k~ miles on these plugs runs good and hauls ***..if anything it's running slightly rich which would be the reason theres soot on the ring?

Thanks again happy holidays!

A/F looks good from pic. Center is caramel colored. Strap has color change all the way back which indicates to high a heat range. Go down one step. Carbon around top edge could be rich idle.

Not an expert though.
