Spark plug color...

[Sonic03svt]

Just a quick question...I hope.

I pulled the plugs out of my car this morning and and confused by the color...

I did a search and looked at the NGK webiste, but my plug color doesn't fall into their catagories.

They look really red or rust color to me. The website only addresses light tan coloring, but like I said, they looked like they had a lot more red tint than tan. Anyway, does anyone have any idea what the diagnosis is?

Heres a pic...

I'm just a little concerned about the tune. TIA.

A red tent is the perfect color. You have no problems. The colors you dont want is a real white color which indicates a lean condition, a really black color which indicates a too rich problem, or a green tent which means you have coolant going into the cylinder from a bad head gasket. No worries, man... all is good.

I just changed my plugs and had the same color, also the same oil on the threads.

They look PERFECT.

Awesome!! I was concerned about running too lean, but I guess that I'm safe!!

Thanks for the help!

That oilly looking stuff is probably anti-seize compound. A spark plug in aluminum heads best friend.

Thats what I was hoping, I used anti-seize on the new ones also.

Yeah, it's anti-seize compound.
