Spark plug condition?

[HECTOFL5TYPER]

Pulled one out can anyone tell me if it’s normal ? Only 9k miles.

Might need to double check the gap, but for the most part they look normal.

The second to last one stands out just from how much more gray it is than the rest, not sure if that means anything given that spark plugs are made to create explosions

Reason I’m asking is a friend of mine who’s a mechanic said it looked like I was burning coolant. In my defense I am tuned, was running e40. Again this is only one spark plug. I’ll pull the other 3 tomorrow and post pictures I don’t known how to tell between good or bad spark plugs.

if you arent losing coolant or having issues then i wouldnt really worry about it.. id check gap as suggested previously.. also cant really judge much from A spark plug

Thanks. That’s correct no coolant was lost or needed. Car has about 8k miles.

They look normal. Burning coolant usually steam cleans everything in the cylinder(s), including plugs.

Borescoping is a good way to confirm head gasket coolant leaks, but use a good scope that won't lose the tip inside the cylinder. Otherwise look down the spark plug holes with a mini-Maglite. Piston tops should all look the same.
